Light and airy with a hint of crispness around the edges, these yeast-risen doughnuts don’t fall too far from their wheat-filled counterparts. In order to keep them light, the dough is not rolled and cut as wheat-based doughnuts are. Instead the dough is left loose, helping it to rise beautifully. When it comes time to fry, the dough is either spooned in for doughnut holes or piped onto parchment for easy round doughnuts. Note that instant yeast can be added to this recipe to add more yeast-risen flavor and texture, but the sourdough starter can be used alone as the leavening.
