In a 5-quart bowl, mix the yeast, water and salt. Add all the flour, then use a wooden spoon to mix until all ingredients are uniformly moist. It is not necessary to knead or continue mixing once the ingredients are uniformly moist. This will produce a loose and very wet dough.
2.Cover with a lid (not airtight). I cover loosely with plastic wrap. Allow the mixture to rise at room temperature until it begins to collapse, about 2 hours, but no more than 5 hours.
3. After rising, the dough can be baked immediately, or covered (non completely airtight) and refrigerated up to 14 days. The dough will be easier to work with after at least 3 hours refrigeration.
4. On baking day, prepare a pizza peel (I use a regular plate since I do not own a pizza peel) by sprinkling it liberally with cornmeal to prevent the bread from sticking when you transfer it to the oven. Uncover the dough and sprinkle the surface with flour. Pull up and cut off a 1-pound (grapefruit-size) piece of dough (serrated knives are best). Store the remaining dough in the bowl and refrigerate for baking at another time.
5. Hold the mass of dough in your hands and add a little more flour as needed so it won't stick. Create a smooth ball of dough by gently pulling the sides down around to the bottom, rotating the ball a quarter-turn as you go. While shaping, most of the dusting flour will fall off. The bottom of the loaf may appear to be a collection of bunched ends, but it will flatten out during resting and baking. Shaping the loaf this way should take no more than 1 minute.
6.Place the dough on the pizza peel. Allow the loaf to rest for about 40 minutes. It does not need to be covered. The bread may not rise much during this time.
7. Twenty minutes before baking, place a pizza stone on the center rack of the oven. If you don't have a baking stone, use another baking sheet. Remove any upper racks. Place a broiler pan on a rack below the pizza stone or on the floor of the oven. Preheat oven to 450 F.
8. When the dough has rested for 40 minutes, dust the top liberally with flour, then use a serrated knife to slash a 1/4-inch-deep cross or tic-tac-toe pattern into the top.
9.Slide the loaf off the peel and onto the baking stone. Quickly but carefully pour 1 cup of hot water into the broiler tray and close the oven door.
10.Bake for about 30 minutes, or until the crust is nicely browned and firm to the touch. Allow the bread to cool completely, preferably on a wire cooling rack.
