Biscotti or cantucci are Italian almond biscuits that originated in the Tuscan city of Prato. They are twice-baked, oblong-shaped, dry, crunchy, and may be dipped in a drink, traditionally Vin Santo. Versions with smaller pieces are known as biscottini or cantuccini.

A biscuit, in most English speaking countries, is a flour-based baked and shaped food item. Biscuits are typically hard, flat, and unleavened. They are usually sweet and may be made with sugar, chocolate, icing, jam, ginger, or cinnamon. They can also be savoury, similar to crackers. Types of biscuit include sandwich biscuits, digestive biscuits, ginger biscuits, shortbread biscuits, chocolate chip cookies, chocolate-coated marshmallow treats, Anzac biscuits, biscotti, and speculaas.
