   1 1/4  teaspoons     dry yeast -- or 1/2 small cake
                        -- fresh,(9 g)
     1/4  cup           warm water
   3      cups          water -- room temp
     3/4  cup           biga -- *(200 grams)
   7 1/2  cups          all-purpose flour -- unbleached,(1000 g)
   1      tablespoon    salt -- plus,(20 g)
   1      teaspoon      salt

Preparation:

* Biga: starter made from 1/4 tsp dry yeast, 1/4 c warm water, 3/4 cup room temp water, and 2 1/2 cups flour. Let this rise 6-24 hrs at cool room temp, and store in the refrigerator until wanted. Proof the yeast in the warm water. Add 3 c water and the starter, mix till blended. Add flour and salt, mix till dough comes together and pulls off the sides of the bowl. Knead 3-5 minutes in a mixer, longer by hand. Dough will be very soft and elastic. Let rise about 3 hours, shape into 3 round loaves or 2 big flattish ones. If you have baking stones, place loaves on whatever you use to slide them into the oven with, or on your baking sheets on sprinkled corn meal if you don't. Let rise about 1 hour. Preheat oven to 450F, and 5 to 10 minutes before baking flour the loaves' tops and dimple them with your fingers. Bake 50-60 minutes for big loaves, 30-35 minutes for little ones. Tap the loaves to test for doneness (hollow=done) and cool on a rack. I don't know if The Italian Baker is still in print, but it is an excellent book, well worth hunting for.
