Cantucci, also known as biscotti di Prato, are traditional Tuscan almond cookies that are twice-baked to achieve a crunchy texture. They are made by combining flour, sugar, eggs, almonds, and a hint of vanilla, then shaping the dough into long logs and baking them until golden brown. The logs are then sliced into individual cookies and baked again until they are crispy and dry. Cantucci are often enjoyed dipped in Vin Santo, a sweet dessert wine from Tuscany. These cookies are a beloved Tuscan treat and make for a delightful end to a meal.
