The main ingredient in traditional bread pudding is stale bread. This dish is designed to use up leftover bread, which is cubed or torn into pieces and combined with a mixture of milk, eggs, sugar, and spices. The liquid mixture soaks into the bread, creating a soft, custardy texture when baked. Raisins or other dried fruits are often added for sweetness and texture. Bread pudding is a versatile dessert that can be flavored in various ways, such as with vanilla, cinnamon, or chocolate, making it a comforting treat enjoyed in many cultures.
