Cut one ounce of salt pork into small square pieces, also two tablespoonfuls of crust from off a fresh loaf of bread cut the same way ; fry them together in a frying-pan with an ounce of butter for about two minutes, adding a boiled potato cut into small squares, a pinch of chopped parsley, half a pinch of chopped chives, half a pinch of salt, and the same quantity of pepper.
