biscotti

Biscotti (plural of Italian biscotto, roughly meaning "twice baked") are crisp Italian cookies often containing nuts or flavored with anise. Traditionally, biscotti are made by baking cookie dough in two long slabs, cutting these into slices, and reheating them to dry them out. A basic recipe is a mix two parts flour with one part sugar with enough eggs to create a stiff batter. To the mixture baking powder and flavorings such as anise, chocolate, or nuts are added. The slabs are baked once for about twenty-five minutes. They are then cut up into individual cookies and baked again for a shorter period. The longer this second baking is, the harder the cookies will be. Originally the cookies were twice-baked so they could be stored for long periods of time; because of this storage potential, they historically have been used widely by explorers and soldiers.
