Cantucci, also known as biscotti di Prato, are traditional Tuscan almond cookies. They are twice-baked, which gives them a crunchy texture. Cantucci are typically made with a mixture of almonds, flour, sugar, eggs, and a hint of vanilla. The dough is shaped into long logs, baked until golden brown, then sliced into individual cookies and baked again until crisp. Cantucci are often enjoyed dipped in Vin Santo, a sweet dessert wine. They are a delicious and addictive treat that is perfect for dunking.
