The fancy French word for dough shaped in a ball is boule. Bread makers use the same technique to form a tight ball of dough for a large loaf of bread and for small individual dough balls such as these fluffy dinner rolls. While it takes two hands to form a large loaf into a boule, you can make a small one with just one cupped hand. If you get really good at it, you can even do two balls at once—one in each hand!
