A pasty (pronounced PASS-tee, rhymes with "nasty" — never "PAY-stee") is a savory hand pie made from a flaky pastry crust folded over a filling of diced beef, potatoes, onions, and rutabaga (or turnip), seasoned simply with salt and pepper, and baked until golden. It's substantial, portable, and deeply satisfying — the kind of food that was designed to get a person through a twelve-hour shift underground.
A proper pasty weighs about a pound. The crust is thick enough to hold together in a lunch pail but tender enough to eat. The filling is raw when it goes in, cooking inside the sealed pastry for about an hour until everything melds into a dense, savory pocket. No gravy inside — the juices from the meat and vegetables create their own.
Every pasty shop has its own recipe. Some use ground beef, some insist on diced. Some add carrots, some consider that a violation. Some make the crust with lard, some with butter, some with shortening. These differences are not minor. They are the subject of fierce, generations-long debate.
