Ingredients:

Directions:

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

Add the flour directly into the container with the full batch of room-temperature, batterlike ripe chef

52

Stir vigorously to add fresh oxygen to the mixture

53

This will form a stiff consistency more like a stiff dough than a batter

54

This firm texture is important for ripening levain, because a dense rather than loose levain creates delicious sour bread without an overpowering tangy bite

55

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

56

The levain should have doubled in volume

57

The texture will be somewhat light, with many tiny bubbles throughout

58

Do not let the levain stand for longer than 10 hours, or the yeast will become exhausted and not raise the final dough

59

This recipe yields 18 ounces of levain

60

Day 1: Combine the flour and water in a tall 2 to 3-quart clear plastic container with a lid

61

Stir well to make a thick, soft dough

62

The exact consistency of the dough will vary with the brand of flour or water at this point to adjust the texture

63

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

64

Day 2: 3/4 cup plus 2 tablespoons (4 ounces) 20 percent bran wheat flour 1/2 cup (4 fluid ounces) spring water

65

The chef should have almost doubled in volume

66

You will see tiny bubbles on the surface, and you might notice a slight musty smell

67

Add the flour and water to the mixture and stir vigorously to distribute the fresh ingredients and add fresh oxygen to the chef

68

The texture will still be like a soft dough

69

You may add a little more flour or water to make this texture, if necessary

70

Scrape down the sides, cover and place in a moderate (70 degree) draft-free place for 24 hours

71

Day 3: 3/4 cup plus 2 tablespoons (4 ounces) 20 percent bran wheat flour 1/2 cup (4 fluid ounces) spring water

72

It will have almost doubled in volume and be quite bubbly

73

Add the flour and water, and stir well to make a thick batter

74

(You may have to add a little more water if your flour's absorption level is high)

75

With a marker pen, mark the level of the chef on the side of the container

76

Scrape down the sides, cover tightly, and let stand in a moderate (70 degree) draft-free place for 24 hours

77

It should now be loose in texture, like a pancake batter

78

It will have doubled in volume from the last addition of flour and water

79

The chef may rise and fall, but as long as it doubles at some point during this last period, it's fine

80

You now have a fully ripe chef ready to transform into a levain

81

If you don't want to make the levain immediately, the chef can be refrigerated for up to 3 days
