San Francisco Sourdough

  1. Combine the levain and water in a 2-quart clear plastic container with a lid.
  2. Break up the levain well with a wooden spoon or squeeze through your fingers until it is broken up.
  3. Stir until the levain is partly dissolved and the mixture is slightly frothy.
  4. Add the flour and stir with a wooden spoon until very thick and sticky.
  5. Scrape down the sides with a rubber spatula.
  6. Cover with plastic wrap and put in a moderately warm (74 to 80 degree) place for 24 hours.
  7. Final dough: 2 cups (16 fluid ounces) spring water 5 1/2 to 6 1/2 cups (27 to 32 ounces) organic white flour with germ 1 tablespoon (3/4 ounce) fine sea salt
  8. Combine the poolish and water in a 6-quart bowl.
  9. Break up the poolish well with a wooden spoon and stir until the poolish becomes loose and the mixture slightly frothy.
  10. Add 2 cups (10 ounces) of the flour and the salt; stir until well combined.
  11. Add just enough of the remaining flour to make a thick mass that is difficult to stir.
  12. Turn out onto a lightly floured surface and knead, adding remaining flour when needed, until dough is firm and smooth, 15 to 17 minutes total.
  13. The dough is ready when a little dough pulled from the mass springs back quickly.
  14. Shape the dough into a ball and let it rest on a lightly floured surface while you scrape, clean, and lightly oil the largest bowl.
  15. Place the dough in the bowl and turn once to coat with oil.
  16. Take the dough's temperature: the ideal is 78 degrees.
  17. Cover with a clean damp towel or plastic wrap and put in a moderately warm (74 to 80 degree) draft-free place until doubled in volume.
  18. Deflate the dough by pushing down in the center and pulling up the sides.
  19. Cover with a clean damp towel or plastic wrap and put in a moderately warm (74 to 80 degree) draft-free place for 30 minutes.
  20. Transfer the dough to a lightly floured board and knead briefly.
  21. Shape into a tight ball.
  22. Cover with a clean damp towel or plastic wrap, and put in a moderately warm (74 to 80 degree) draft-free place for 30 minutes.
  23. Divide the dough into 2 equal portions.
  24. Flatten each with the heel of your hand on a lightly floured board.
  25. The dough may be very soft and loose at this point.
  26. Shape into 12-inch-long torpedoes.
  27. You may also choose to shape the dough into rounds.
  28. Place the torpedoes, seam side up in a well-floured couche*.
  29. Cover with a clean damp towel or plastic wrap.
  30. Put in a moderately warm (74 to 80 degrees) draft-free place until increased in volume about 1 1/2 times, or until a slight indentation remains when the dough is pressed with a fingertip.
  31. Place rounds on a cornmeal-dusted surface to rise.
  32. Preheat the oven and baking stone to 450 degrees, 45 minutes to 1 hour before baking.
  33. The oven rack must be in the center of the oven.
  34. If it is in the lower 1/3 of the oven the bottom of the breads may burn, and if it is in the upper 1/3, the top crusts may burn.
  35. Gently roll one loaf from the couche onto a lightly floured peel so that it sits seam side down.
  36. Using a very sharp, serrated knife or a single-edged razor blade, score the loaf by making quick shallow cuts 1/4 to 1/2-inch deep along the surface.
  37. Using the peel, slide the loaf onto the hearth.
  38. Quickly repeat the process with the second loaf.
  39. Quickly spray the inner walls and floor of the oven with cold water form a spritzer bottle.
  40. If there's an electric light bulb in the oven, avoid spraying it directly; it may burst.
  41. Spray for several seconds until steam has filled the oven.
  42. Quickly close the door to trap the steam and bake 3 minutes.
  43. Spray again in the same way, closing the door immediately so that steam doesn't escape.
  44. Bake until loaves begin to color, about 15 minutes.
  45. Reduce heat to 425 degrees and bake until loaves are a rich caramel color and the crust is firm, 15 to 20 minutes.
  46. To test for doneness, remove and hold the loaves upside down.
  47. Strike the bottoms firmly with your finger.
  48. If the sound is hollow, the breads are done.
  49. If it doesn't sound hollow, bake 5 minutes longer.
  50. Cool completely on a wire rack.
  51. Note: If the dough temperature is higher than 78 degrees, put it in a cooler than (78 degree) place like the refrigerator, until the dough cools to 78 degrees.
  52. If it is lower than 78 degrees, put in it a warmer than 78 degree place until the dough warms to 78 degrees.
  53. The point is to try to keep the dough at 78 degrees during its fermentation.
  54. If you do have to move the dough, be gentle and don't jostle it, or the dough may deflate.
  55. *Couche?French for "couch" or "resting place".
  56. This is a simple holding device you make yourself for proofing long loaves like logs, torpedo shapes, and baguettes.
  57. Using well-floured canvas or linen towels create folds to separate loaves while hold them securely next to each other during proofing.
  58. Use a length of fabric at least a yard long.
  59. Place 12 to 16-inch wooden blocks cut from 2 by 4's at either long end to contain the loaves.
  60. Or substitute large books to contain the loaves.
  61. Add the flour directly into the container with the full batch of room-temperature, batterlike ripe chef.
  62. Stir vigorously to add fresh oxygen to the mixture.
  63. This will form a stiff consistency more like a stiff dough than a batter.
  64. This firm texture is important for ripening levain, because a dense rather than loose levain creates delicious sour bread without an overpowering tangy bite.
  65. Scrape down the sides, cover tightly, and let stand in a cool to moderate (about 70 degrees) draft-free place for 8 to 10 hours.
  66. The levain should have doubled in volume.
  67. The texture will be somewhat light, with many tiny bubbles throughout.
  68. Do not let the levain stand for longer than 10 hours, or the yeast will become exhausted and not raise the final dough.
  69. This recipe yields 18 ounces of levain.
  70. Combine the flour and water in a tall 2 to 3-quart clear plastic container with a lid.
  71. Stir well to make a thick, soft dough.
  72. The exact consistency of the dough will vary with the brand of flour or water at this point to adjust the texture.
  73. Scrape down the sides with a rubber spatula, cover tightly with lid and let stand in a moderate (about 70 degree) place for 24 hours.
  74. Day 2 3/4 cup plus 2 tablespoons (4 ounces) 20 percent bran wheat flour 1/2 cup (4 fluid ounces) spring water
  75. The chef should have almost doubled in volume.
  76. You will see tiny bubbles on the surface, and you might notice a slight musty smell.
  77. Add the flour and water to the mixture and stir vigorously to distribute the fresh ingredients and add fresh oxygen to the chef.
  78. The texture will still be like a soft dough.
  79. You may add a little more flour or water to make this texture, if necessary.
  80. Scrape down the sides, cover and place in a moderate (70 degree) draft-free place for 24 hours.
  81. Day 3 3/4 cup plus 2 tablespoons (4 ounces) 20 percent bran wheat flour 1/2 cup (4 fluid ounces) spring water
  82. It will have almost doubled in volume and be quite bubbly.
  83. Add the flour and water, and stir well to make a thick batter.
  84. (You may have to add a little more water if your flour's absorption level is high).
  85. With a marker pen, mark the level of the chef on the side of the container.
  86. Scrape down the sides, cover tightly, and let stand in a moderate (70 degree) draft-free place for 24 hours.
  87. It should now be loose in texture, like a pancake batter.
  88. It will have doubled in volume from the last addition of flour and water.
  89. The chef may rise and fall, but as long as it doubles at some point during this last period, it's fine.
  90. You now have a fully ripe chef ready to transform into a levain.
  91. If you don't want to make the levain immediately, the chef can be refrigerated for up to 3 days.
