The Cornish Pasty is commonly associated with Cornwall, United Kingdom. It differs from a pie as it is made by placing the filling on a flat pastry shape, usually a circle, and folding it to wrap the filling, crimping the edge to form a seal. The result is a raised semicircular package. The traditional Cornish pasty is filled with diced beef, sliced potato and onion, and baked.
