Biscotti means "twice baked" in Italian, and double baking is the secret to making these popular, crunchy cookies. To make biscotti, the dough is shaped into an oblong loaf and baked. The baked loaf is then cut into slices that are baked again until they become dry and hard. As durable as they are tasty, these cookies keep extremely well and are a good choice to give as a gift. They are delicious served with fresh fruit, and are perfect for dunking in coffee or a sweet dessert wine such as vin santo.
