Biscotti
Biscotti is the Italian plural term for any type of biscuit or cookie. However, in English, biscotti is commonly used to refer specifically to cantucci ( Italian: [kanˈtuttʃi]), also known as biscotti di Prato or biscotti etruschi, which are Italian almond biscuits originating in the city of Prato, in Tuscany. These biscuits are twice-baked, oblong-shaped, dry, crunchy, and may be dipped in a drink, traditionally Vin Santo. Smaller biscotti may be known as biscottini or cantuccini. In Italy, the term biscotti encompasses a wide variety of biscuits and cookies of different shapes, sizes, flavours, and fillings. The word biscotto, used in modern Italian to refer to a biscuit (or cookie) of any type, originates from the Medieval Latin word biscoctus, meaning 'twice-cooked'. It characterised oven-baked goods that were baked twice, so they became very dry and could be stored for long periods of time. Such non-perishable food was particularly useful during journeys and wars, and twice-baked breads were a staple food of the Roman legions.
