Cantucci, also known as biscotti di Prato, are almond-based cookies that originated in Florence. These crunchy and twice-baked cookies are typically made with flour, sugar, eggs, almonds, and a hint of vanilla. They are traditionally served with a glass of Vin Santo, a sweet dessert wine. The cookies are often dipped in the wine to soften their texture and enhance their flavors. Cantucci are a beloved treat in Florence and make for a delightful souvenir to bring back home.
