The longer you wait to use the proto-dough, the tangier the bread will be.

Preparation
Step 1
Mix first 4 ingredients in bowl of heavy-duty mixer. Add 2 cups flour; stir to blend. Cover bowl with kitchen towel. Let rise in warm draft-free area until doubled in volume, about 1 1/2 hours.
Step 2
Using dough hook, mix in 1 1/3 cups flour and salt at lowest setting. Increase speed slightly; knead dough 5 minutes, adding more flour by tablespoonfuls if dough sticks to sides of bowl. Let dough rest 15 minutes. Knead on low 5 minutes. Scrape dough from hook into bowl. Remove bowl from stand. Coat rubber spatula with nonstick spray. Slide spatula under and around dough, coating dough lightly. Cover bowl with kitchen towel. Let dough rise until doubled in volume, about 1 hour.
Step 3
Turn dough out onto floured surface and fold over on itself several times to flatten. Divide in half. Shape each half into 4x8-inch rectangle. Make 1 shallow lengthwise slash down each.
Step 4
Sprinkle large rimmed baking sheet with cornmeal. Space loaves on sheet 3 inches apart. Dust tops with flour. Cover with plastic; let rise in warm draft-free area until doubled in volume, about 1 hour.
Step 5
Place 13x9x2-inch metal baking pan on bottom of oven. Position rack at lowest level of oven; preheat to 500°F. Place bread in oven. Quickly pour 1/2 cup water into metal pan; close oven door. Bake 5 minutes. Add 1/2 cup water to pan. Quickly close door; reduce oven temperature to 425°F. Bake loaves until puffed and golden, about 20 minutes. Transfer to rack; cool 15 minutes. Serve warm or at room temperature.
