SOURDOUGH STARTER

Steps:

• Make seed culture: Combine 1 ounce of the flour and 2 ounces pineapple juice in a large glass or small nonreactive bowl. Cover tightly with plastic wrap and leave at room temperature, stirring with a wet spoon twice a day. Bubbles should appear after 24 to 36 hours. After 48 hours, add 1 ounce flour and remaining pineapple juice, stirring to incorporate. Re-cover with plastic wrap and leave at room temperature, stirring with a wet spoon twice a day. When it is foamy, in 1 to 4 days, combine 2 ounces flour and 1 ounce filtered or spring water in a medium nonreactive bowl. Add seed culture, stirring to incorporate, and re-cover with plastic wrap. Stir twice a day to aerate.
• When mixture has doubled in bulk, in 1 to 2 days, convert it into a starter: Combine 12 ounces flour and 9 ounces filtered or spring water in bowl. Add 4 ounces of seed culture mixture (discard the rest, or use to make a second starter) and mix until fully incorporated. Transfer to a lightly floured surface and knead for 2 minutes. It should have the consistency of bread dough. Transfer to a nonreactive bowl and let rest at room temperature until it doubles in size, about 4 to 8 hours. Knead lightly, then store in container with tight-fitting lid (container must be large enough to let starter triple in bulk). Store in refrigerator.

SOURDOUGH PUMPERNICKEL BREAD

Steps:

• The day before making the bread:.
• Mix proofed starter, rye flour, and water in a bowl.
• This will make a wet, pasty barm (starter).
• Cover the bowl with plastic wrap and ferment at room temperature for 4 to 5 hours or until the the sponge becomes bubbly and foamy.
• Immediately put it in the refrigerator overnight.
• Bread baking day:.
• Remove the rye barm (starter) from the refrigerator one hour prior to making the dough.
• After chill is off the barm, stir together the flour, sugar, cocoa, salt and yeast in large mixing bowl.
• Add the rye barm, bread crumbs and oil and mix on low speed with paddle attachment until the ingredients form a ball.
• Add additional water if the dough ball does not pick up all the flour, or more flour if the dough seems too wet.
• With dough hook attachment mix on loaw speed for 4 to 5 minutes.
• Add more flour as needed to make a smooth pliable dough ball. It should be tacky but not sticky.
• Note: Rye bread will become gummy if you mix too long, so try to make all adjustments early and minimize the mixing and kneading process.
• Transfer dough to lightly oiled bowl, rolling it around to coat it with oil.
• Cover bowl with plastic wrap and ferment at room temperature for 2 hours or until doubled in size.
• Sprinkle small amount of flour on the counter and carefully transfer the dough to the counter (try not to degas the dough).
• Divide the dough in 2 equal pieces and shape them into boules or rectangle for sandwich bread.
• Line baking sheet with parchment (or use proofing basket) and sprinkle with cornmeal, smolina flour or coarse whole-rye flour.
• If making sandwich bread, lightly oil 8 1/2 by 4 1/2 inch bread pan(s).
• Transfer the dough to the pans, mist the dough with spray oil and loosely cover with plastic wrap or a towel.
• Proof at room temperature for approximately 90 minutes, or until the dough crests 1 inch above the lip of the bread pan at the center, or rises to 1 1/2 times it original size.
• For Freestanding Loaves:.
• Preheat the oven to 450°F, placing a baking stone on the middle shelf and a broiler pan or cast-iron skillet on lower shelf (to provide steam).
• Score the loaves to allow for expansion.
• Transfer the dough to the baking stone.
• Pour 1 cup hot water into the steam pan and quickly close the door.
• After 30 seconds open the door and spray the oven walls with water.
• Repeat twice more at 30 second intervals.
• After the final spray, lower the oven temperature to 400°F and continue to bake for another 20-30 minutes. Checking the breads and rotating 180 degrees, if necessary, for even baking.
• When done, the bread should register 200°F in the center and sound hollow when thumped on the bottom.
• For Loaf Pans:.
• Place pans on baking sheet and place in the oven (middle rack).
• Bake for 20 minutes, then rotate the sheet pan 180 degrees for even baking.
• Continue baking another 20 to 30 minutes, or until loaves register 185-195°F in the center and sound hollow when thumped on the bottom.
• Remove finished loaves from the pan and cool on a rack for at least 1 hour before slicing.

SAN FRANCISCO SOURDOUGH BREAD

Steps:

• Do ahead
• To make the starter, combine all of the ingredients in a mixing bowl. If using a mixer, use the paddle attachment and mix on the lowest speed for 1 minute, then increase to medium speed for about 30 seconds. If mixing by hand, stir for about 2 minutes, until well blended. The starter should feel doughlike and tacky or slightly sticky; if not, stir in additional flour or water as needed.
• Transfer the starter to a lightly floured work surface and knead for about 30 seconds. Place it in a clean, lightly oiled bowl, cover the bowl loosely, and leave at room temperature for 6 to 8 hours, until the starter increases to about 1 1/2 times its original size. If you plan to use the starter the same day, allow 1 more hour of fermentation so that it nearly doubles in size. Otherwise, put the starter in the refrigerator for up to 3 days.
• To make the dough, cut the starter into 10 to 12 pieces and put them in a mixing bowl. Pour in the water and mix with the paddle attachment on the lowest speed or with a large spoon for about 1 minute to soften the starter.
• Add the flour and salt, as well as the yeast (unless you're making the "purist" version). Switch to the dough hook and mix on the lowest speed, or continue mixing by hand, for 2 minutes, to form a coarse ball of dough that's very tacky and slightly warm. Let the dough rest for 5 minutes.
• Mix on medium-low speed or by hand for 4 minutes more, adding flour or water as needed to make a soft, supple, slightly sticky ball of dough.
• Transfer the dough to a lightly floured work surface and knead by hand for 1 minute, then form it into a ball. Let the dough sit uncovered for 10 minutes, then do a stretch and fold, either on the work surface or in the bowl, reaching under the front end of the dough, stretching it out, then folding it back onto the top of the dough. Do this from the back end and then from each side, then flip the dough over and tuck it into a ball. Cover the dough and let it rest for 10 minutes. Do another stretch and fold, then immediately form the dough into a ball, place it in a clean, lightly oiled bowl large enough to contain the dough when it doubles in size, and cover the bowl.
• If using the mixed method with instant yeast, refrigerate the dough immediately. If making the "purist" version, without instant yeast, let the dough sit at room temperature for 1 1/2 to 2 hours before refrigerating; it won't rise very much, but it should show signs of growth and continue to rise in the refrigerator. Either version will be ready to use the next day and for up to 3 days. (If you plan to bake the dough in batches over different days, you can portion the dough and place it into two or more oiled bowls at this stage.)
• On baking day
• For the "purist" version, remove the dough from the refrigerator about 4 hours before you plan to bake; after 2 hours, shape it (see instructions for lean bread, page 48), then let it proof for 2 hours before baking. For the mixed method, remove the dough from the refrigerator 2 hours prior to baking and shape it right away. Remove only the portion you wish to bake: 19 ounces (539 g) for a 1-pound (454 g) loaf; 28 ounces (794 g) for a 1 1/2-pound (680 g) loaf, and so on. You can also bake the entire amount of dough as a large, 3-pound (1.36 kg) miche (round country loaf) or as a large torpedo loaf. See chapter 1, page 20, for instructions.
• Proof for 2 hours as a freestanding loaf, in floured proofing baskets, or on proofing cloths. The dough should increase in size to 1 1/2 times its original size and be springy yet hold an indentation when pressed with a finger. It may spread as it rises, but it will grow taller as it bakes.
• If using a baking stone, about 45 minutes before baking preheat the oven to 500°F (260°C) and prepare the oven for hearth baking (see page 30). Otherwise, just preheat the oven to 500°F (260°C) about 20 minutes before baking.
• Just before baking, score the dough with whatever style of design you prefer (see page 29). Transfer the dough to the oven, pour 1 cup of hot water into the steam pan, then lower the oven temperature to 450°F (232°C), or to 425°F (218°C) if baking a large miche.
• Bake for 12 minutes, then rotate the pan and continue baking for 15 to 35 minutes, or longer, depending on the size of the loaf; a large miche could take up to 75 minutes to bake. When fully baked, the crust should have a rich, caramelized color, the loaf should sound hollow when thumped on the bottom, and the internal temperature should be about 200°F (90°C) in the center. Cool on a wire rack for at least 1 hour before slicing or serving.
• Variations
• For country-style pain au levain, you can substitute whole wheat flour or other whole grain flours for an equal amount of bread flour (by weight), in which case you'll need to increase the water by about 1/2 tablespoon (0.25 oz / 7 g) for every 3 1/2 tablespoons (1 oz / 28.5 g) of whole grain flour you use. A typical pain au levain would substitute 2 to 3 ounces (56.5 to 85 g) of whole grain flour for an equal amount of bread flour, but there really is no limit.
• One of the best variations of this bread has crumbled blue cheese (or chunks of any good melting cheese) and toasted nuts or seeds (walnuts are highly recommended). Add nuts to the dough during the last minute of mixing, using about 25 percent nuts to total flour. Since the total flour in this recipe is about 34 ounces (964 g), counting the flour in the starter, about 8.5 ounces (241 g) of nuts would be just right. With the cheese, you can add anywhere between 25 to 45 percent of the weight of the flour; so that would be 8.5 to 15.3 ounces (241 to 434 g). Fold the cheese in by hand at the end of the mixing or roll it into the dough during shaping (see the crusty cheese bread recipe on page 121).

PAIN AU LEVAIN

Steps:

• Make the sourdough starter. Combine all of the ingredients in a mixing bowl. If using a mixer, mix on the lowest speed using the paddle attachment for 1 minute, then increase to medium speed for about 30 seconds. If mixing by hand, use a large spoon and stir for about 2 minutes, until well blended. The starter should feel dough-like and tacky or slightly sticky; if not, stir in additional flour (if too sticky) or water (if dry) as needed.
• Transfer the starter to a lightly floured work surface and knead for about 30 seconds. Place it in a clean, lightly oiled bowl, cover the bowl loosely, and leave at room temperature for 6 to 8 hours, until the starter increases to about 1 1/2 times its original size. If you plan to use the starter the same day, allow 1 more hour of fermentation so that it nearly doubles in size. Otherwise, put the starter in the refrigerator for up to 3 days.
• Make the dough: cut the starter into 10 to 12 pieces and put them in a mixing bowl. Pour in the water, then add the yeast (if using) and mix with the paddle attachment on the lowest speed or by hand with a large spoon for about 1 minute to soften the starter. Add the flour and salt.
• Switch to the dough hook and mix on the lowest speed, or continue mixing by hand, for 3 minutes, to form a coarse ball of dough that's very tacky and slightly warm. Let the dough rest for 5 minutes. Resume mixing on medium-low speed for 3 minutes more or knead by hand for 3 minutes, adding more flour or water as needed to make a soft, supple and tacky by not sticky ball of dough.
• Knead the dough by hand for a few seconds, then form it into a ball. Let the dough sit uncovered for 10 minutes, then do a stretch and fold, either on the work surface or in the bowl. To do this, reach under the front end of the dough, stretching it toward you, then fold it back onto the top of the dough. Do this from the back end and then from each side, then flip the dough over and tuck it into a ball. Cover the dough and let it rest for 10 minutes. Repeat this entire process two more times, completing all repetitions within 30 minutes. Immediately form the dough into a ball, place it in a clean, lightly oiled bowl large enough to contain the dough when it doubles in size, and cover the bowl tightly.
• If using instant yeast, refrigerate the dough immediately. If not using the yeast, let the dough sit at room temperature for 2 hours before refrigerating; it won't rise very much, but it should show signs of growth and continue to rise in the refrigerator. With or without the instant yeast, both will be ready to use the next day and for up to 4 days. (If you plan to bake the dough in batches over different days, you can portion the dough and place it into two or more oiled bowls at this stage.)
• To bake the no-yeast version, remove the dough from the refrigerator about 4 hours before you plan to bake it; after 2 hours, shape it, then let it proof (i.e., rest covered with a cotton or linen dishtowel) for 2 hours before baking. For the yeast version, remove the dough from the refrigerator 2 hours prior to baking and shape it right away. Remove only the portion you wish to bake: 19 ounces for a 1-pound loaf; 28 ounces for a 1 1/2-pound loaf, and so on. You can also bake the entire amount of dough as a large, 3-pound miche (round country loaf) or as a large torpedo loaf. Gently transfer it from the bowl to a lightly floured work surface, being careful to degas it as little as possible. The shaped dough won't increase in size very much, but it will begin to swell and grow. If it grows to 1 1/2 times its original size in less than 2 hours, move on to scoring and baking it.
• If using a baking stone, about 45 minutes before baking, preheat the oven to 500 degrees. Otherwise, set the oven to 500 degrees about 20 minutes before baking and preheat a baking sheet covered with parchment paper. Place a small sheet pan or lasagna pan under the stone or oven rack to act as a steam pan.
• Just before baking, score the dough by using a blade or sharp knife to cut ½-inch deep lines into it. (A pound sign or cross are two suggested scoring patterns.) Transfer the dough to either the warmed baking sheet or stone. Pour 1 cup of hot water into the steam pan (a watering can or tall plastic pitcher is best for this), then lower the oven temperature to 450 degrees or to 425 if baking a large miche. (Note: If your oven has a glass window, cover it with a towel when adding the water to prevent cracking, then remove after a few minutes.)
• Bake for 12 minutes, then rotate the pan and continue baking for 15 to 25 minutes, or longer, depending on the size of the loaf; a large miche could take up to 75 minutes to bake. When fully baked, the crust should have a rich, caramelized color; the loaf should sound hollow when thumped on the bottom; and the internal temperature should be about 200 degrees in the center. Cool on a wire rack for at least 1 hour before slicing or serving.
