Once the dough has finished rising, use a bench scraper to cut the dough into even pieces. For this particular recipe, I cut the dough into 32 pieces. It should be noted that those challah buns become hamburger-bun-sized (perfect for turkey sandwiches the next day). If you want smaller challah rolls, then cut the dough into 64 pieces . . . and enlist the entire family to help. After all, making challah is more fun with a group.
