Flake up the fish free from skin and bone, mash the potatoes and mix them together; season with half the parsley, pepper and salt. Mince the bacon and onion very finely; put them into a frying pan with the butter and fry for a few minutes. Stir in the fish and potatoes and turn about until thoroughly hot through. Pour over the gravy or milk and again make thoroughly hot. Heap on to a dish, and garnish with the rest of the parsley. Serve very hot.
Time: 10 minutes.
