The easiest way to divide these rolls is to use a large dough scraper or a large, flat-edged knife. Use plenty of flour on your work surface and hands. Rub the dough scraper or knife with flour and sprinkle a thin trail of flour along the cut line. Press the dough scraper firmly into the dough and push one section of the dough away from the other before lifting the dough scraper. A floured spatula is also helpful for transferring the rolls to a baking sheet.
