Turn the dough onto a lightly greased surface and divide in half. Pat each section into a thick rectangle, 9X13-inches or thereabouts (doesn't have to be exact). Roll the dough up starting from the long edge, pressing out any air bubbles or seams with the heel of your hand, and pinch the edge to seal. Arrange seam side down on a large baking sheet lined with parchment paper (I use separate baking sheets for each loaf). You can slash several gashes in the top of the bread now or wait until after
