Six large potatoes and two onions, with half a pound of salt pork.
Cut the pork into dice, and fry to a light brown.

Add the onions, and brown them also.

Pour the remaining fat into a large saucepan, or butter it, as preferred.

Put in a layer of potatoes, a little onion and pork, and a layer of the fish cut in small pieces, salting and peppering each layer.
A tablespoonful of salt and one teaspoonful of pepper will be a mild seasoning.

A pinch of cayenne may be added, if liked.
