A pasty (Cornish: Pasti, Hoggan, incorrectly written as pastie) is a type of pie, originally from Cornwall, United Kingdom. It is a baked savoury pastry case traditionally filled with diced meat, sliced potato and onion. The ingredients are uncooked before being placed in the unbaked pastry case. Pasties with traditional ingredients are specifically named Cornish pasties. Traditionally, pasties have a semicircular shape, achieved by folding a circular pastry sheet over the filling. One edge is crimped to form a seal.The vowel 'a' in pasty is 'pure' (pronounced /ˈpæsti/). Thus, "pasty" sounds like "past" and does not sound anything like "paste".Oggy is a slang term used in Britain which comes from a Cornish term for the pasty.
