Daniel T. DiMuzio, Baking and Pastry instructor at Culinard, The Culinary Institute of Virginia College, is the author of Bread Baking: An Artisan's Perspective, a new textbook on the art of artisan bread baking.  Dan has owned his own artisan bakery, managed and consulted with numerous other bakeries, and studied and baked with master bakers such as Didier Rosada and Jeffrey Hamelman. 

Dan was kind enough to discuss his new book with long-time TFL member Eric Hanner (EHanner) and myself.

Floyd: My first reaction to your book is "Wow, a textbook on Artisan Baking written in English for a North American audience!  Artisan baking has really made it, hasn't it?!?"

Dan: Well, yes, I’d say it has made it. That’s a testament, I guess, to the growing number of sophisticated palates among Americans and others in the world. It used to be hard to find good bread, and you had to ask around to find anything approximating a good baguette. Now you can actually go to most supermarkets and get decent, par-baked breads from companies like LaBrea, Ecce Panis, or others. Heck, 20 years ago croissants were considered exotic, and now they’re as common as a cheese danish.

The thing is, even though there was a sort of renaissance in craft baking over the 90’s, the textbooks covering bread for culinary students didn’t really change to keep up with the new awareness about that. There was still a focus upon a somewhat arbitrarily chosen “12 Steps of Baking”, and “artisan breads” were seen as some kind of avant garde offshoot that could be covered completely in a separate 15-page chapter.

One of the reasons I wrote this book was to present an entirely different perspective on bread in culinary education. All bread can be “artisan” if it is prepared by an educated baker who respects the ingredients, mixing, and fermenting that are crucial to creating good flavor and texture. So that can include anything from baguettes and ciabatta to pan breads or hot dog buns. It isn’t all about brick ovens or flour-covered hearth loaves. My hope is that culinary schools will embrace the idea that artisanal bread baking is an entirely different philosophy of baking, and that its principles should be applied to almost any bread -- not just a specialized set of very old recipes.

Floyd: Do you have any idea how many culinary programs there are now teaching artisan baking in North America?  Have you noticed an upsurge in interest in artisan baking among students enrolled at Culinard in the past few years?

Dan: When Wiley sent out first drafts of the chapters for review, the people chosen for the task were baking instructors from a real cross section of the schools out there. There were larger private ones with high-profile names, medium-sized vocational schools, and fairly small community colleges as well. The one common refrain we’d hear from them was that they wanted to find a culinary textbook that covered the renewed awareness about great bread baking in depth.

I don’t know how many programs now embrace artisanal perspectives in bread baking, but it is many more than I first thought. The only schools I know about that have a “dedicated” bread curriculum now (not associated with pastry) are Johnson & Wales, the CIA, and the French Culinary Institute. There are probably a few more I don’t know about, so if anyone reading this knows of any that I missed, accept my apologies.

In my opinion, there’s a very real, practical divide between the things that appeal to a pastry chef and the things that motivate bread bakers. There are people who are passionate about both areas (Nancy Silverton comes to mind), but that’s more of an exception. Pastry chefs are usually very artistic in their outlook, and they are obsessed with aesthetics. Sugar sculptures, petit fours, gorgeous cakes – all of these come from a desire to please with the eye. And while these confections can be good to eat occasionally, their flavor or texture often takes a back seat to impressive looks. That’s possibly why most wedding cakes don’t have a taste that matches their $1000-2000 price tag.

Bread baking is more visceral than aesthetic in its appeal, and I think the conscientious practitioners are better seen as craftspeople than as artists. It’s part science and part skill, and the goal is to make something great to eat – looks are important, but only in a secondary way. So, in too many cases, pastry students often aren’t as passionate about good bread as the students from the savory end of the culinary school. Pastry people mostly want to improve their artistic skills, and while they may want to include bread baking as part of their skill set, they often don’t see it as essential. I really think there’s more of an affinity between the “savory” culinary students and a curiosity about making great bread. When I started showing students in Culinard’s garde manger program (they make pate, hors d'oeuvres, etc,) how to make their own dough for focaccia and tiny buffet sandwiches, they were usually very appreciative.

Floyd: As a (former?) bakery consultant, you must have insight into the economics of running a bakery.  I always wonder how folks make it pencil out with the low volume and high ingredient and labor costs that go into making bread.  Is it as hard to make a living baking as I imagine it is?  What are some of the tricks to making a bakery successful (besides baking great breads)?  Location?  Sell lots of coffee?

Dan: It’s very, very hard. You have to love bread baking to be a successful artisan baker, and you might even have to refashion your definition of success. During the 90’s a lot of people tried to change careers away from being office types to starting a bakery, pastry shop, or even a restaurant. Most of them had no idea how physically and financially draining the move would be. Food magazines and stylists had done a good job of making that work seem very chic, cerebral, and meditative. While you may find solace in owning an artisan bakery, it has most of the same challenges as owning any small business, with the added hurdles of starting your work day at 2 to 3am and working 12 hour days.

So, yeah, location is very essential, and if Panera Bread wants to lease the same great spot you do, guess who the landlord is going to sign? I think that independent artisan bakeries will continue to thrive in bigger cities and around many university campuses, because enough people there will go out of their way to get exceptional quality in bread and other foods. In most of America, though, there’s been a big shakeout over the last 10 years, and even in some big cities the shops that used to thrive are getting less and less traffic. Some of that is due to Panera deceiving people into thinking that they embrace artisanship, some is due to good par-baked breads being available in supermarkets, and I think the rest is about the novelty wearing off and people just wanting to do all their shopping in one trip at the grocery.

Floyd: Though your book is geared more for people seeking to make a living as a baker, I think there is quite a bit that serious home bakers would find valuable in it.  I know I particular found your chapter on designing a formula insightful.

Dan: Thanks, Floyd. I certainly hope that more bakers or baking students see that chapter and the worksheets as ways of thinking more in terms of “formulas” and less in terms of “recipes.” Ultimately, that’s how you become a baker – professional or not – and not just a recipe reader. Designing your own formula forces you to think analytically about the baking process, and how the ingredients don’t just come together in the bowl, but actually affect and change each other. Eventually, that understanding helps you to troubleshoot your problems with anyone else’s formulas, as well.

Floyd: I like that you offer many of the formulas both with preferment and without.   More often than not the version with preferment will have a better flavor, won't it?

Dan: That’s a good question, and I think my opinion about it has changed a lot over the years. Aspiring artisan bakers in the 90’s were looking for the magic bullet that would transform their bread from just OK to being extraordinary. Whenever a different ingredient, technique, or equipment choice made its way across the ocean to us, we’d embrace it as the “essential” idea of the moment, even when it might contradict or ignore earlier “artisan” perspectives we’d recently discovered.

Pre-ferments were part of that search for a magic bullet. A lot of folks got seriously into using levain (sourdough), then Professor Raymond Calvel educated people about “pate fermentee” – which is just leftover baguette dough -- , and others traveled to France and saw poolish being used extensively. Eric Kayser promoted a more liquid type of levain by the mid-90’s, and fans of Italian bread had discovered Carol Field’s excellent “The Italian Baker,” which featured biga. Any of these pre-ferments could add flavor and nice aromas to your bread, and – importantly -- they shortened the time you had to wait before the dough was ready to divide and shape. In bread competitions like the Coupe du Monde, some of the USA contestants even used two or three pre-ferments to add complexity to their flavor profile or adjust the speed of the process.

What got lost in all that excitement about different pre-ferments was that in the 1920’s there were Frenchmen who made a long-fermented straight dough (using the “Direct” method) that had no pre-ferments. James MacGuire writes extensively about it in his article in the Art of Eating, 2006, Nos. 73-74. It was still very, very good in flavor due to its long bulk fermentation time (5 hours or so), and its light texture and eggshell crust were different somehow from baguettes made with poolish or old dough. Not better or worse -- just different. Raymond Calvel (who taught Julia Child how to make bread) insisted that, despite the fact that he promoted “pate fermentee” as an ideal pre-ferment, he really thought that the “direct method” baguettes of his early career were his favorites. The big downside of the direct method was that it took 4-5 hours of bulk fermentation, and probably 7-8 hours overall. Pre-ferments used in conjunction with manufactured yeast could shave 2 hours or more off of that time.

So any or all of those methods for making bread are good, and they’ve all had their periods of favor. Preferences there are often a matter of taste. One technique might work better with certain styles of bread than others. Straight doughs are only advisable if you can dedicate a lot of time (at least 5 hours) to fermenting the dough before it reaches maturity, and you should use less yeast to achieve that. Sourdoughs (levain breads), of course, aren’t going to BE sourdough unless you use a sour pre-ferment. But any dough leavened primarily with manufactured yeast can be made as a straight dough, if you have the time.

Floyd:  Interesting.  Thank you.

Eric: First let me say I find your new book very interesting from a number of standpoints. I like the fact that it is a teaching reference book. I know much of the material in the beginning chapters because I have read it at one time or another in a variety of places but this is the first time I have been able to scan the pages and be reminded about the basics of the craft. There isn’t so much detail that it would be hard to read and focus on, just the broad strokes to spark an interest.

Dan: Thanks. Of course, the book was originally conceived as a tool for use in culinary classrooms. I tried to get into the detail that I thought was critical to understanding WHY artisan bakers do what they do without burdening the reader with so much data that it might induce a coma (!). We wanted to give the bread instructor a way of providing background (of their choosing) while they taught bread fundamentals from an artisanal perspective.

Eric: I see there is also a web component for the teacher’s side with lessons and further material. That would be interesting to see also from my perspective.

Dan: You know, you’re not the first person to ask me about that, and I’m going to TRY to get as much of that stuff as possible available to readers who aren’t in school. I doubt that the quizzes or exams would be made available, for obvious reasons, but possibly the worksheets for formulas could be made downloadable. Still, Wiley has the copyright to the book, so we’d need their cooperation and agreement.

Eric:
I think this would make a good gift for a young person who is expressing an interest in cooking or baking. Sort of a leg up on further education. I have a person in mind now that might appreciate some early knowledge.

Dan: Thanks again for the kind words. I would say that the book makes the most sense as a reference or instructional work for very serious bread bakers. People who are happy with being casual in their approach – and that’s still great, by the way – might want to find it in a bookstore and check it out before getting it, since it isn’t really like a typical bread book. You can also check out parts of it at online bookstores, to get a general sense of it.

Eric: One of the things I have been trying to get my hands around this year is improving the aroma and taste of my sourdough breads. Do you have an opinion on what a good compromise would be for a feeding regimen and storage temperature to promote the esters I am trying to create? You have a nice section on the general subject on Page 66 under fermentation. I’m looking for something a little more specific for a white starter.

Dan: I have pleasant and not-so-pleasant news: The pleasant news is that if you are willing to be disciplined in your approach to creating and maintaining a sourdough starter, you can usually reproduce whatever flavor profile you discover that appeals to you. So using the exact same feeding schedule, fermentation times, mix temperatures, ambient temperatures and hydration will get you what you want when you know what that is.

Unfortunately, only you can decide what’s optimal and what isn’t. I’ll provide a framework for beginning, but you’ll need to customize it to your ingredients, your environment, and your lifestyle.

I keep a firm levain (after it has stabilized) at a 60% hydration, around 70°F using something like KA All Purpose flour. I try to stick with a twice-a-day feedings, 12 hour intervals if possible. I determine the weight of ripe starter I’m going to feed, and then I use enough fresh flour and water (combined) to create a newly-fed mass that is three times the size of the original piece of ripe starter. Again, I do that every 12 hours, so you usually need to discard some ripe starter as you go to keep from making a barrel of it.

For three-times-a-day feeding, I’d probably only double it every time instead of tripling it. For once-a-day, I’d probably quadruple or even quintuple the size of the ripe nugget of levain. All of these feeding schedules may produce usable levain, but the flavor of the differently scheduled feedings will yield some differences, with less feeding yielding more acidity (lower pH) and less yeast activity, and more frequent feeding producing less acidity and greater yeast activity.

You can change the hydration of the feedings, as well, but keep in mind that wetter starters ferment more quickly and need more frequent feedings or larger feedings, or both.

Eric: A couple of things that I think are problems for home bakers is 1.) Knowing when the proofing is done and 2.) Getting the dough in during the window of opportunity that will deliver a good result. In my own case I was distracted while writing this note and missed the chance to get my Whole Wheat into the oven on time. It’s a little over proofed and totally my fault. In a commercial kitchen, people are paying attention. In my home office there are many distractions.  Is it true that I can extend my window of opportunity for baking if I lower the dough temp by a few degrees? I know the process will slow but are there any side effects in terms of structure?

Dan: Well, at the risk of covering stuff you already know, let me just state that the classic three points of control are time, temperature, and hydration. So, yes, you could go for a slightly cooler final dough temperature (or DDT, as I think Jeff Hamelman calls it) and slow things down a bit without many other noticeable effects. I wouldn’t recommend going anywhere below 74°F for a same-day bake, or you might slow things too much. Slower fermentation rates do give you a wider window for realizing that your product is ready for baking.

Eric: I haven’t read them all yet but I really am enjoying the side comments from the noted Artisan Baker Profiles in the book. I think these are excellent resources for aspiring bakers. Knowing what the key words are ahead of time would give a candidate the confidence to know they are prepared. Also I think it is important to understand what the job is really all about and that baking is still evolving.

Dan: It never occurred to me that readers not in school would find the opening list of key concepts interesting, but that’s great. And I’m glad you like the profiles – they do help point out to aspiring artisans what some of the essentials are in making a bread business work. Another thing I wanted to do there – and I don’t know yet if I succeeded – was to portray how there are different ways of looking at what’s essential and what’s not.

Eric: I noticed on Page 182 talking about using pre ferments, you didn’t reduce the amount of yeast in the final dough when using a Poolish. I have believed that I should reduce some because of the growing activity I created in the Poolish with the small amount of yeast hours before. Am I wrong about this?  In general I try to use as little yeast as necessary for all the reasons you talk about creating acids and esters over time.

Dan: You’re right that you should use as little yeast as you think is necessary to produce a selected bulk fermentation time and a mature, easily handled dough. No matter who’s formula you’re using, you should feel free and not at all “wrong” to make minor adjustments to things like yeast quantity, hydration levels, or fermentation times to get the results you prefer. I selected yeast levels that I believe work for me when I designed those formulas, but if the parameters I selected (2 hr ferment, 3 hr ferment, whatever) don’t fit what you want to do, you should change them. Just keep a record of those changes so you don’t have to keep re-discovering them.

Eric:
Thank you Daniel for making your self available to us. As it turns out your new book is a lot like this community. We tend to be oriented more toward techniques and practices rather than just a source for recipes.  “Bread Baking, An Artisan’s Perspective” is much the same.

Dan: I appreciate your positive comments about the book, and I’m happy to make myself available to answer questions whenever I may be here, now or in the future. I have been surprised to see the interest from many home bakers to this book, despite its technical, school-oriented perspective. There seems to be a thirst out there for more in-depth explanations about certain baking concepts, and I’m just very happy to play a small part in providing some of that.

Bread Baking: An Artisan's Perspective is available from Wiley & Sons right now.

If you have additional questions for Dan, ask them below.

May 14, 2009 update:  The question and answer period is now closed.  Thank you again for your time, Dan!

Soft Pretzels - Alton Brown Style

I love soft pretzels - who doesn't?  I just never seem to get them outside of fair settings.

And then the other week, Alton Brown did a show on homemade pretzels - it was a sign! So I went to the food network's site and I grabbed the recipe. (http://www.foodnetwork.com/recipes/alton-brown/homemade-soft-pretzels-recipe/index.html)

The Ingredients:

1 1/2 cups warm (110 to 115 degrees F) water

1 tablespoon sugar
2 teaspoons kosher salt
1 package active dry yeast
22 ounces all-purpose flour, approximately 4 1/2 cups
2 ounces unsalted butter, melted
Vegetable oil, for pan
10 cups water
2/3 cup baking soda
1 large egg yolk beaten with 1 tablespoon water
Pretzel salt (note, I simply used Kosher salt)

ALTON: Combine the water, sugar and kosher salt in the bowl of a stand mixer and sprinkle the yeast on top. Allow to sit for 5 minutes or until the mixture begins to foam.

So Alton's all into proofing the yeast - and I must say that I only do this because the instructions say so.  At some point I'll stop since I'm really only convinced this is a leftover from poor production methods of old - but look, it bubbles:

ALTON: Add the flour and butter and, using the dough hook attachment, mix on low speed until well combined. Change to medium speed and knead until the dough is smooth and pulls away from the side of the bowl, approximately 4 to 5 minutes.

Now it's all about letting the KitchenAid do the work. I add the melted butter and the flour. You may notice Alton's recipe does specify flour by weight. I actually do have a scale where I can zero out my mixing bowl with ingredients, so I'm able to pour 22 ounces of flour exactly. From here, I let the mixer do it's thing for 5 minutes until the dough is nice and ready:

ALTON: Remove the dough from the bowl, clean the bowl and then oil it well with vegetable oil. Return the dough to the bowl, cover with plastic wrap and sit in a warm place for approximately 50 to 55 minutes or until the dough has doubled in size.

Rising time. Recipe calls for an hour, but this is fast-acting - in 30 minutes, I'm more than doubled:

ALTON: Preheat the oven to 450 degrees F. Line 2 half-sheet pans with parchment paper and lightly brush with the vegetable oil. Set aside.

Bring the 10 cups of water and the baking soda to a rolling boil in an 8-quart saucepan or roasting pan.

In the meantime, turn the dough out onto a slightly oiled work surface and divide into 8 equal pieces. Roll out each piece of dough into a 24-inch rope. Make a U-shape with the rope, holding the ends of the rope, cross them over each other and press onto the bottom of the U in order to form the shape of a pretzel. Place onto the parchment-lined half sheet pan.

Place the pretzels into the boiling water, 1 by 1, for 30 seconds. Remove them from the water using a large flat spatula. Return to the half sheet pan, brush the top of each pretzel with the beaten egg yolk and water mixture and sprinkle with the pretzel salt. Bake until dark golden brown in color, approximately 12 to 14 minutes. Transfer to a cooling rack for at least 5 minutes before serving.

I tear my into 8 pieces and lightly oil my counter so I can roll these into ropes and form them into pretzel shapes. I'll admit that it's not as supple as I'm expecting it to be, but that's okay. While I do this, I have water boiling on the stove and the oven preheating:

Hint from me to you - do put in the baking soda before the water is boiling - if you think you see white crusty stuff on the sides of the pot, you do. I added the baking soda while the water was boiling and got a mini-science experiment. Luckily no spillover, but I laughed. I basically boiled each pretzel for 30 seconds and scooped it out with a wire scoop (this gives the pretzel texture):

At this point, I give the pretzels an egg wash and bake them for 13 minutes. Look what I get:

If you're wondering - but is it a chewy, doughy piece of pretzel goodness? Well - take a look at this crumb:

Yes, this is good stuff - I will be making this again!

 

Whole Wheat Sourdough English Muffins

JMonkey

My daughter basically lives on these for breakfast. I save up old starter over the week in the fridge and make these both during the week and over the weekend. Super easy, and they freeze very well. Simply split and freeze. When you want one, pop it directly in the toaster from the freezer. I learned this recipe with volumetric measures, and never bothered to convert to grams. I adapted this recipe and converted it to whole wheat from a posting at The Fresh Loaf from KJKnits.

Ingredients

Sourdough starter: 1/2 cup (stiff or wet, makes no difference)
Milk: 1 cup if you use wet starter; 1.25 cups if you use stiff
Whole wheat flour: 2 cups
Honey: 1 Tbs
Salt: ¾ tsp
Baking soda: 1 tsp

Semolina flour or cornmeal, for dusting

Dissolve the starter into the milk and then add the flour.  Stir to combine, cover with a plate or plastic, and leave out for 8 hours or overnight. It’ll be pretty wet – don’t worry, it’ll firm up by morning.

The next morning, add the honey, salt and baking soda and mix well.  Turn onto a lightly floured surface and knead for a few minutes with wet hands. With your fingers, flatten it out to 3/4" thick  and cut with a biscuit cutter or a drinking glass into rounds.  Reflatten the scraps to make additional muffins. You’ll get 10-12 muffins.  Place muffins on a surface dusted with semolina, cornmeal or flour cover and let them rise for about 45 minutes to an hour.

Spray griddle or skillet lightly with spray oil or add a little butter. (Actually, if it’s nonstick, you may not need any grease at all.) Heat to medium high and cook muffins for about 5 minutes on each side, or until browned on the top and bottom and cooked through.  These have great griddle spring and rise quite a bit.  They’re done when the sides are firm.

Split with a fork and toast if you like. As noted above, they freeze very well.

Cherry Pecan Pain au Levain

I've always liked the walnut raisin pain au levain Dan Leader sells at Bread Alone Bakery near me, and I've been wanting to try something like this for awhile and finally got around to it this week, but with cherries and pecans.

Both Susan's yeasted version on her Wild Yeast blog and SteveB's version on his Bread Cetera blog gave me a craving for cherry pecan bread when I saw their photos....thanks for the ideas you two, your baked goods are so mouthwatering and professional looking...(I am unworthy of breadblogging in the same sphere as you two!)

I made this as a sourdough-only version and mixed about 30% whole wheat and 2.5% rye with AP flour. This mix gave a nice dark-colored but light-textured open crumb that tasted good with the fruit and nuts. You could obviously substitue rasins and walnuts, or anything else you can think of. I find it especially tastes great sliced, toasted, and served with cream cheese, and lasts a long time.

I soaked the cherries for a bit too long as they were a little too mushy and a some color washed out, but the bread tasted great, I'll be making this again a lot I think. It was very easy.

Here are the loaves just before slashing and loading into the oven, after their overnight cold retarding:

Here's the formula:

Pecan Cherry Pain au Levain

Makes 2 large 2.5 lb batards or oblong loaves.

Levain Build

% flour of levaingrams
starter (100% hydration with WW flour) 32.1% 45
warm water 85.7% 120
All-Purpose flour 100.0% 140

Final Dough

% flour final doughgrams
All-Purpose flour 66.4% 750
100% whole wheat flour 31.0% 350
100% whole rye flour 2.7% 30
flour subtotal 100% 1130
 
warm water 69.5% 785
sea salt 2.0% 23
ripe levain 27.0% 305
dried pitted sour cherries, soaked   240
toasted pecans   240

1)  12 hours before making final dough, create the levain using some ripe starter that has been fed and doubled. Mix well and cover in bowl until levain has risen to over double but has not yet begun to collapse, aprox. 10-12 hours at 65-70F. Toast the pecans at 350F for 10-20 minutes and let cool, then coarsly chop and set aside. Soak dried sour cherries in water overnight and strain next morning before making final dough.

2)  When levain is ripe, create final dough by mixing warm water with levain to dissolve. Mix all flours and salt in large bowl until evenly distributed, then add watered levain to flour mix with dough whisk, spoon, or hands until well combined. Cover and let rest for 1 hour at @ 70F. Tip dough onto counter, knead in the cherries and pecans lightly, and french fold for approx. 10 minutes with short 1-2 minute rests as needed to scrape together dough or relax it, and tuck in the fruit/nuts. The cherries and pecans may fall out and it will be quite messy at first, but eventually the dough will come together into a neat lump after 5-6 minutes or so. At end of kneading, round out the dough so that fruit/nuts are tucked inside and good skin of dough is on outside. Place dough in lightly oiled container and cover to rest for 30 min. After 30 min., turn out dough onto lightly oiled counter to give it one good gentle stretch and letter fold, then place dough back into oiled covered container. Repeat one more stretch and fold after another 30 minutes, then let dough continue to rise until doubled at @ 70F (approx. 2 more hours).

3)  Shape dough into 2 batards, place batards in floured couche, cover well so loaves don't dry out, and let loaves cold proof overnight at 40-50F for approx. 8-10 hours. Next morning, place loaves in warmer area (65-70F) while oven preheats for 45 minutes to 450F. Bake loaves on oven stone with steam (I pour 1 cup hot water from tea kettle into pre-heated cast iron pan on oven floor) at 450F for 15 minutes, then turn heat down to 400F for another 30-35 minutes until center registers 200-205F with instant read thermometer and crust is well-browned.

On a slightly different note: my last few batches of bread have been coming out smelling and tasting better than ever, I think it may just be this new flour I was able to pick up in a 50lb bag from Bread Alone Bakery down the road from me. It is an All-purpose flour from Canada with 11.5% protein, not sure about ash content. Anyone ever used or heard of this Oak AP flour before?I like it a lot. It handles nicely in dough.

Commercial Yeast

The three most common types of commercial yeast are:

Fresh yeast:
Truth be told, fresh yeast, which is also known as cake yeast, is hard for home bakers to find these days. They are sold as little “cakes” that must be kept refrigerated, and they go bad after a few days. Many professional bakeries, however, still use fresh yeast, and so many bread formulas are written with fresh yeast in mind. Typically, breads that rise for 1.5 to 2 hours in bulk and 1 to 1.5 hours shaped call for fresh yeast at 2% of total flour weight.

Many recipes use much, much less yeast than that, however, and they ferment for much longer, which gives the bread more flavor.

Active dry yeast: This is the kind of yeast that you’re most likely to find in your grocery store. Typically, you’ll want to use about 1 to 2 tsp per loaf and, if the formula calls for fresh yeast, you’ll need to measure out 40% of that weight to convert to active dry.

Active dry yeast needs to be “proofed” before using, which means it needs to be dissolved in about ¼ to ½ cup of lukewarm water (about 90 degrees F or so).

Instant yeast:
This is what many amateur bakers prefer to use. In grocery stores you'll often find it labels "Rapid Rise Yeast" or "Bread Machine Yeast."  It looks like active dry yeast, but it retains many more living yeasts in each grain. As a result, there’s no need to proof it – just add the yeast directly to the dry ingredients. If the formula calls for fresh yeast, measure out 1/3 of that weight for instant yeast. If the recipe calls for active dry yeast, cut the measurement by about 25 percent.

How to Develop Sour Flavor in Sourdough

How to Develop Sour Flavor in Sourdough

I just posted this as a response to a query, but thought that it deserved to be posted as a separate topic.  I spent months trying to figure this out, and there was so much inaccurate information posted on the internet on the subject, that I thought this would be useful to lots of people trying to figure out the "secret" of developing sour flavor in sourdough.  It's a heck of a lot simpler than most people seem to think.

In short, there are three key factors in the development of flavor in sourdough:

1. Ash Content of Flour (which affects the Buffering Capacity of the dough)
2. Fermentation Time
3. Fermentation Temperature

Everything else is either secondary or, in some cases, simply wrong.

The ash content of the flour is a key issue for development of total acidity (TTA - Total Titratable Acids) and flavor.  The higher the ash content, the higher the buffering capacity.  The buffering capacity of the flour reduces the volatile acidity (pH) of the dough, allowing the bacteria to work longer before they over-acidify their environment and stop producing acids and flavor compounds.  In addition, ash content is critical for allowing the bacteria to develop amino acids and volatile flavor compounds that contribute to that signature sourdough flavor.  While sourness can be obtained using a low ash content flour, the bread will contain a lesser overall acidity, and will contain fewer amino acids and volatile flavor compounds that contribute to flavor.  All purpose flour normally does not have a high enough ash content to allow substantial flavor development.  High gluten flour (aka bread flour) usually does.  Whole wheat and rye breads have an even higher ash content, which is why people are often more successful in developing sourness and flavor in doughs containing these flours.

The fermentation time must be LONG, meaning 12 to 20 hours.  Acidity and flavor develops during fermentation of the dough, and it takes the bacteria a long time to do it.  If you ferment your bread for less than about 8 hours, you'll get a very tasty, but non-sour bread.

The fermentation temperature should be between 20C and 30C.  Any less, and you're simply slowing down the bacteria in their quest to eat food and develop flavor.  Any more, and you're overheating them and hindering their growth.  However, anything within the indicated range is just fine.  Bacteria do produce some different volatile flavor compounds below 25C than they do above 25C, so this is one way to fine-tune the flavor of your bread, if you so desire.

For more information on the above, here's an excellent, freely available paper on the subject:

Here's a VERY SIMPLE procedure for creating a bread with a fully-developed sour flavor with any starter (I've got a collection of three of them, including Carl's 1847 Oregon Trail Starter, and this technique works wonders with all of them).

Step 1 - Make a fairly stiff dough using 5% to 20% starter
Step 2 - Place in oiled bowl, cover with plastic wrap, and let sit at room temperature for 12-15 hours (no need to punch down, worry, fret, or whatever... just let it sit).
Step 3 - Gently remove from bowl* and bake.

Yep, that's it.  After months of trying to figure out how to get that sourdough flavor, trying various complicated methods involving overnight refrigeration, letting the starter go sour, multiple starter stages, chanting of mystical incantations, etc., I found out that you just make the dough and let it sit on your kitchen counter.  How's that for uncomplicating things?

Hope this clarifies things a bit.  Good luck with your sourdough baking!

* I usually scrape the dough from the bowl with a spatula directly onto an oiled baking sheet, slash the top, and bake.  No shaping and re-proofing necessary if you're simply making a round boule or carefully stretching the dough into baguettes.  If you want to shape the bread otherwise, you should do so 3 to 5 hours before baking.

11 Apr 2008 - Made some updates and changes based on the excellent comments posted in response.

13 Apr 2008 - Added note regarding shaping, clarifications regarding the effect of ash content on acidity, and a note that different flavor compounds are produced below and above 25C.

Chocolate cherry sourdough bread




I've been wanting to make this bread for years, ever since I first had a bite of chocolate cherry bread from Zingerman's in Ann Arbor, Mich. I've tried making this several times over the past few months, all of them flops. Pancakes, covered in charcoaled chocolate (Yum-o!) were the usual products of my labors. Not this time. I finally got think I nailed it. Here's how I made it (note: These cups are Laurel's Kitchen-style cups. Don't fluff up the flour and spoon it in -- dig deep and let it settle.

Ingredients:

  • 120 grams or 1/2 cup active sourdough starter (100% hydration)
  • 340 grams or 2.25 cups bread flour
  • 8 grams or 1 1/8 tsp salt
  • 210 grams or 3/4 cup + 3 Tbs Water
  • 150 grams or 1 cup dried tart cherries
  • 125 grams or 1 scant cup big chunks of chocolate

    I've found I get more flavor out of my sourdough if I let the starter ripen at above 80 degrees. It's not necessary, though. Just make sure your starter is ripe. The night before, dissolve the starter into the water as best you can. Mix the salt with the flour (You can try using all-purpose -- I think all-purpose has better flavor and texture for sourdough, personally -- but I find that bread flour gives this bread the heft it needs to rise well despite the weight of the goodies). Then dump the flour into the starter slurry and mix it all up together until it's all hydrated. The dough should be very tacky and maybe a little sticky, but not super sticky. We're shooting for the texture of wet French dough, not ciabatta.

    Cover the bowl with plastic or a plate, and let it sit at room temperature (about 70 degrees F, more or less) for about 12 hours (anywhere from 10-14 should be fine). Once it's ready, it should look something like the photo to the left.

    Meanwhile, pour some boiling water over the cherries. If you can't find dried tart cherries (Trader Joe's sells them around Boston), dried cranberries will usually do almost as well. Let the fruit soak for about 15 minutes, drain and then place them on towels or paper towels to dry. You want the interior wet enough so that the fruit won't draw moisture from the dough, but dry enough on the exterior so they won't turn your dough into soup (it can happen -- believe me, I know). When the fruit is ready, mix it up with the chocolate in a bowl, and have it handy.

    Flour a workspace lightly, and then gently turn the dough out onto the board. With wet hands, lightly pat the dough into a rectangle. Stretch the dough to about twice its length, and then spread 1/4 of the chocolate cherry mixure in the center. Fold one-third of the dough on top, and again, spread 1/4 of the mixture on top. Fold the final third of the dough like a letter, and then turn the dough one-quarter. Follow the same procedure, and then cover the dough. Let it rest for about 15 minutes. Here's a photo sequence to show you what I'm talking about.



    Stretch and spread.


    Fold and spread.


    Fold again. Then turn the dough one quarter and repeat! Easy-sleazy. (That's the final product above. I skipped a few steps in the photos. It's well-established that stretch and fold only remains exciting and engaging for ... oh ... no more than three photos, I believe..)

    Folding the chocolate and cherries into the bread ensures that the vast majority of the goodies stay protected from the fierce heat to which you're going to subject the dough in order to get that lovely, crunchy crust we all adore. The yummy stuff is not as evenly distributed as it would be were it mixed in from the beginning, but uneven distribution is highly preferable to charcoal. Trust me.

    Now, after letting the dough rest for 15 minutes, gently shape the dough into a boule, and place it in a well-floured banneton. I splurged a while back and bought one of my own, but you can easily construct a makeshift banneton out of a bowl and a well-floured linen napkin.

    I like to let my sourdough proof in the makeshift proof-box you see to your right. I pour a cup or two of boiling water in there and close it up. It'll stay within 3-4 degrees of 85 degrees F for about 90 minutes. I then pour in another cup or two of hot water.

    After 3 hours, my bread looked like this.




    About an hour beforehand, I'd put my cloche in the oven and preheated it to 500 degrees F, but if you don't have a cloche, a dutch oven or oven-safe casserole will do. If you don't have that, just use your baking stone and steam the oven. If you don't have that, just put the bread on a baking sheet. Once the bread was scored, I baked it covered for 30 minutes, and uncovered for about 17-18 minutes, and then let it cool an hour (can you believe it?) until we dug in. I had a minor mishap with a bit of my bread sticking to the peel, thus the odd shape to the left. It didn't disuade us from gobbling it all up with 48 hours though.

  • pumpkin bread in window
    I love pumpkin bread and muffins any time of the year, particularly with chocolate chips in it and while sipping a cup of dark coffee, but pumpkin bread seems particularly appropriate this time of year.

    This is a recipe for your standard pumpkin quick bread; yeasted pumpkin breads are rare, though not unheard of. Fresh pumpkin can be be used, though I usually take the easy way out and just use canned pumpkin puree. Whole wheat flour can also be substituted for some or all of the all-purpose flour for a change of pace.

    Because the moisture content of the pumpkin can vary, as it can in the flour, the recipe recommends between 3 and 4 cups of flour. I used about 3 1/2 cups, but don't be afraid to trust your gut and adjust according to conditions.


    Pumpkin Bread

    Pumpkin Bread

    Makes approximately 12 muffins, 3 small loaves, or 1 large loaf
    1 3/4 cup (1 15 oz. can) pureed pumpkin
    1 1/2 cup brown sugar
    1/2 cup (1 stick) butter, softened
    3 eggs
    3-4 cups all-purpose unbleached flour
    2 tablespoons baking powder
    1 teaspoon ground cinnamon
    1/2 teaspoon salt
    1/2 teaspoon ground nutmeg
    2 cups chopped walnuts or chocolate chips


    Preheat the oven to 350.

    Combine the pumpkin, brown sugar, butter, and eggs and mix until creamy. In a separate bowl, combine all of the dry ingredients except the nuts or chocolate chips. Mix 3 cups of the dry ingredients into the wet ingredients, then add as much of the 4th cup as necessary to achieve the proper consistency (moist, but thick enough to stand a spoon in). Add the nuts or chocolate chips and stir in.

    Pour or spoon the batter into greased muffin tins or bread pans. Bake on the center rack until a toothpick poked into the center comes out dry. At sea level, muffins should take between 20 and 25 minutes to bake, small loaves between 25 and 30 minutes, and full sized loaves between 50 minutes and 1 hour.

    Pumpkin Bread

    In lesson one we baked the simplest bread one can bake. It was made up of just flour, salt, yeast, and water.

    As anyone who has ever looked at the ingredients on a store-bought loaf of bread knows, a lot of other ingredients can be found in loaves of bread. How those ingredients affect the flavor, color and behavior of your bread is the focus of lesson two.

    We'll also bake a loaf to compare to the simple one we made in lesson one.

    As one would guess, additional ingredients change the flavor of your bread. But many of these ingredients also change the behavior of your dough in ways that are not immediately obvious. Knowing a little bit about what to expect when you add a given ingredient to a dough will increase the likelihood of your experiment being a success.

    Common Additional Ingredients

    • Sugars (sugar, honey, molasses). Sugars obviously sweeten and flavor the loaf, but bakers need to keep in mind the fact that they also provide additional food for the yeast. It is common to add a tablespoon or two of sweetener to a loaf of bread, both to feed the yeast and to add a touch of sweetness. But yeasted breads rarely contain as much sugar as one finds in unyeasted quick breads, largely because the added sugar interferes with the proper yeast cycle.

      Sugars also carmalize in the oven, resulting in the rich brown color of crust.


      Notice how the bread from Lesson One, which contained no added sugars, had a very pale complexion.

      Recipes for sugary breads, such as holiday bread, typically call for fewer and shorter rises. Long rises of highly sweetened doughs can result in beery tasting bread, typically not the result you are after when baking a sweet bread.

    • Fats (butter, oils, milk, eggs). Fats enrich and flavor the bread. They also soften the dough and preserve it: whereas a fat-free loaf of bread like a French bread goes stale after only a few hours, a loaf of bread with a small amount of olive oil or butter (like a sandwich bread) retains moisture and will stay fresh longer.

      Fats increase the bulk of your bread. Rarely do you get the kind of large, irregular holes inside an enriched bread as you do in a fat-free bread.

    • Different Flours/Grains. Different grains and types of flour impart different flavors to the bread. They also have varying levels of gluten and sugar: for example, bread flour is higher in gluten than all-purpose flour. Pastry flour is very low in gluten and is typically avoided in yeasted breads because it is incapable of forming proper crumb (the network of air pockets inside of the loaf).

      In most recipes, even those labeled "Whole Wheat Bread" or "Rye Bread", the specialty flours make up no more than half of the flour in the loaf. The remainder is, more often than not, plain old All-Purpose Enriched Unbleached or Bread Flour. The characteristics of regular wheat flour are hard to beat when baking, and a little bit of specialty flour can go a long way in changing the profile of your loaf.

      Whole wheat flour, rye flour, oats, rice, corn meal, mashed potatoes, and semolina flour are all common ingredients. They contain varying amounts of sugar and gluten, so experimentation and comparison are often necessary to achieve the desired result.

    • Other. There really is no limit on what you can add to a loaf of bread: herbs, cinnamon and raisins, garlic, cheese, nuts, dried fruit, olives, even sausage or preserved meats. Use your imagination!

    "Homework" for Lesson Two

    The recipe

    We'll use the recipe from lesson one as the basis for this one, but we'll substitute milk for most of the water, add a little bit butter to soften it up, and add a touch of sugar. I also reduced the salt and yeast from two teaspoons to one teaspoon. When possible, reducing the yeast and increasing the fermentation time results in a better flavor (more on this in lesson three).

    The result is a richer, softer loaf that makes an excellent sandwich bread. Typically I would bake a bread like this in a loaf pan, so that it makes nice, square little sandwiches, but in my example I chose to bake this one on a sheet pan so we can compare it to the loaf from lesson one.

    2 cups all-purpose enriched unbleached flour
    1 cup bread flour (or all-purpose flour, if you do not have bread flour)
    1 teaspoon yeast
    1 teaspoon salt
    1/8 cup sugar
    1 cup warm milk
    2 tablespoons butter
    1/4 - 1/2 cup lukewarm water

    Mix the dry ingredients, then add the wet ingredients. Mix and adjust water until all ingredients are incorporated and the dough is capable of forming a ball. Pour the dough onto a flat, floured surface and knead for approximately ten minutes.

    Return the dough to an oiled bowl and let rise until doubled in size, approximately 90 minutes. Shape the loaf and then let rise again until the desired size is reached, approximately another hour.*

    Bake at 350 for 40 to 45 minutes, until when tapping the bottom of loaf the bread springs back and makes a hollow sound.

    *Note that we're only letting it rise one time for this loaf. Because I added the extra sugar in there, I didn't want it to over-ferment and make the bread taste beery. It is low enough in sugar it probably could have handled another rise, I just didn't feel like risking it tonight!

    Wrap up

    As expected, this loaf was creamier, sweeter, and softer than the loaf we baked in lesson one. The added sugar also carmalized and resulted in a beautiful, brown crust.

    A note on storage: sandwich breads like this are best stored in air-tight plastic bags. Paper bags will help keep the crust its crustiest and are better for storing French breads.

    I stored this loaf in a plastic bag three nights ago. With a bit of enrichment and proper storage, a loaf like this keeps well for up to a week.
