Depending on your region, type of flour used, measuring method, and general humidity, your results may vary as far as dough texture. If you find it very sticky after the bulk rise, turn it out onto a floured surface, and work in a small amount of flour until the dough is still tacky, but not sticky. If you add too much flour, the cornmeal won't stick to the dough, so be sure to add just a bit at a time.
