A pasty (Cornish: Pasti, Tidy Oggy, pronounced /ˈpæsti/ (the 'a' pronounced as in 'cat'), or less commonly pastie) is a type of pie, commonly associated with Cornwall, United Kingdom. It is a baked savoury pastry case traditionally filled with diced meat, sliced potato and onion. Pasties with traditional ingredients are specifically named Cornish pasties. Pasties generally have a semicircular shape, achieved by folding a circular pastry sheet over the filling. One edge is crimped to form a seal.
