• 1 1 to 115 warm water (110 to 115 degrees)
• 1 1/3 1 1/3 1/3 cups (200 grams) unbleached bread flour
• 2/3 2/3 2/3 cup (100 grams) unbleached all-purpose flour
• 2 2 2 TBS (15 grams) whole-wheat flour, preferably coarsely ground
• 2 2 2 TBS (15 grams) whole-grain rye flour, preferably coarsely ground
• 3/4 3/4 3/4 cup (185 grams) water (see method for temperature)
• Large Large mixing bowl, baking stones or tiles, parchment paper
• 5 to 10 into warm water, stir and let stand for 5 to 10 minutes.

Preparation

Step 1

COMBINE the flour, yeast and salt in the bowl of an electric mixer or bread machine.
STIR in the water and biga by hand to form a rough dough.
USING a paddle attachment, beat the dough on medium speed until it is fairly smooth, about 5 minutes. If the dough is very firm, add water. This should be a very soft dough (the large hole structure typical of ciabatta comes from working with very soft, highly hydrated dough - good eplanation of 'wetness' and 'crumb' here). If your dough is not really gloppy, add extra water until the dough is soft enough to spread (your flour might be old or absorbing more water for a variety of reasons).
SCRAPE the dough into a bowl at least three times its size and cover it tightly with plastic wrap. Let it ferment until light and doubled in bulk, about 2 1/2 to 3 hours, turning the dough every 20 minutes for a total of four times. To turn the dough, sprinkle the top of the dough (while still in the bowl) and the work surface with flour; scrape the dough out of the bowl and onto the floured work surface. Sprinkle the dough with flour again, then gently spread the dough out, trying not to deflate the bubbles. Fold it up into a tight bundle by folding the left side into the center, followed by the top, the right side and the bottom. Turn the dough over so that the smooth side is up, and fold it in half again, only if it still feels loose. Place it, smooth side up, into the bowl and cover tightly. NOTE: Best rising is around 75-80 degress F. When colder, you can rise dough in gas oven with pilot light, or in your microwave - place a 1 - 2 cups in a container (or micowave a couple of cups of water) to bring temperature up. This applies to the whole rising process.
AFTER the fourth turn, at 80 minutes, leave the dough undisturbed for 1 1/2 to 2 hours or until well expanded and doubled.
THOROUGHLY flour a baker's couche or two tea towels. Flour the top of the dough and the work surface, then turn the dough out. With a dough scraper, cut the dough in half. Gently stretch the pieces out (approximately 12 by 8 inches) and fold them loosely into thirds, like a business letter, arranging the folds so the last seam is slightly off center. Try to handle the dough as little as possible to avoid deflating it.
PLACE the dough seam side down on the floured cloth and sprinkle more flour over the top. Cover the loaves with folds of the couche or more tea towels. Let them proof until they are very soft and well expanded and barely spring back when gently pressed, about 45 minutes. For higher loaves, use a baguette tray (a couple of large U shapes)
IMMEDIATELY after shaping the dough, arrange a rack on the oven's second-to-top shelf and place a baking stone on it. Clear away all racks above the one being used. Heat the oven to 450 degrees.
WHEN the dough is ready to bake, place a sheet of parchment paper on a peel. Gently flip the loaves onto it so they are seam side up and stretch them very slightly to make them vaguely rectangular. Don't be afraid to handle the dough; the breads will recover in the oven as long as you are gentle.
DIMPLE the dough all over with your fingertips, pressing down to the paper without breaking through the dough. Slide the breads on the parchment paper onto the baking stone. Bake the breads until very dark brown all around, 32 to 36 minutes, rotating them halfway during baking. For a very crisp crust, turn off oven and let bread sit in oven for 10 or more minutes. Let cool on a rack before slicing. Bread is best eaten the same day.
NOTE: Freezes well - Double wrap in plastic wrap, freeze. When defrosting, make sure completely defrosted (I do ten seconds twice on each side while still wrapped for a total of 40 seconds) then ten minutes in a 225 deg. F. oven, turning over after five minutes).
