Cheese and Onion Pie vs Corned Beef Hash

Both dishes share potato, onion, butter, egg and pepper, yet put them to very different work. The Cheese and Onion Pie cooks its onions slowly in butter until soft and lightly caramelized, then folds them into roughly mashed potato with cheddar and milk for a creamy filling, baked inside butter pastry glazed with beaten egg until golden. The Corned Beef Hash fries diced potato and onion in oil and butter until browned and crisp, presses in salty diced corned beef to form a crust, and finishes with eggs cooked until the yolks are still runny and a scattering of parsley.
