When the dough has pulled together, turn it out onto a lightly floured surface and knead until smooth and elastic, about 6 minutes. Lightly oil a large bowl, place the dough in the bowl and turn to coat with oil. Cover with a damp cloth and let rise in a warm place until doubled in volume, about 40 minutes.
Punch dough down, and divide into 8 equal portions. Shape each portion into a 4 inch round loaf. Place loaves on lightly greased baking sheets sprinkled with cornmeal. Cover and let rise in a warm place, free from drafts, until doubled in bulk, about 35 minutes.
