A crumble, also known as a brown betty, is a dish of British origin that can be made in a sweet or savoury version, depending on ingredients used, although the sweet version is much more common. A sweet variety usually contains stewed fruit topped with a crumbly mixture of fat (usually butter), flour, and sugar. A savoury version uses meat, vegetables and a sauce for the filling, with cheese replacing sugar in the crumble mix. The crumble is baked in an oven until the topping is crisp.
