The Cornish Pasty was the original 'portable lunch' for tin miners in Cornwall, England. Its design was purely functional: the thick, crimped crust on the side allowed miners with dirty, soot-covered hands to hold the pasty without contaminating the food they were eating. Once finished, they would throw the 'handle' (the crust) away. To be a protected 'Cornish Pasty,' it must contain beef, potato, swede (turnip), and onion, with no other vegetables allowed. Some historical pasties were made with a savory filling at one end and a sweet jam filling at the other, providing a full two-course meal in one pastry. Today, the Cornish Pasty has 'Protected Geographical Indication' (PGI) status in Europe.
