Biscuits originated from either hardtack ship's biscuits or the art of baking. Modern biscuits can be savory or sweet and are typically small, around 2 inches in diameter and flat. Biscuits are commonly eaten as a snack food worldwide and often contain ingredients like chocolate, fruit, or nuts. In Britain, biscuits like digestives are regularly dunked in tea. Savory biscuits are usually plainer and eaten with cheese. The process of making biscuits involves mixing dry and wet ingredients to form dough, cutting the dough into rounds or shapes, and baking.
