Cobblers is an American recipe consisting usually of a fruit or savoury filling poured into a large baking dish and covered with a batter, biscuit, or pie crust before being baked. The dish is thought to have originated in the early British American colonies. English settlers were unable to make traditional suet puddings due to lack of suitable ingredients and cooking equipment, so instead covered a stewed filling with a layer of uncooked plain biscuits or dumplings, fitted together. The origin of the name cobbler is uncertain, although it may be related to the now archaic word cobeler, meaning “wooden bowl”
