This one is cute. The pasty is attached with the spring so you can:
shake it, shake it. Pasty is different from pies. 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 beef, sliced potato, turnip and onion and baked.
