Turn out dough onto lightly floured surface, cover with towel and let it rest for 10-15 minutes. Knead until smooth, about 5 minutes. Grease cookie sheet, sprinkle with cornmeal. Punch down dough, divide into halves. Shape each half into a round, slightly flaten top of loaf.
Place loaves in opposite corners of cookie sheet.
Oven should be preheated to 375 degrees. Cool on wire racks.
