Grate the raw potatoes and mix them with the cooked mashed potatoes. Add salt, pepper and flour.
Beat the egg and add to mixture with just enough milk to make a batter that will drop from a spoon.
Drop by tablespoonfuls onto a hot griddle or frying pan. Cook over a moderate heat for 3-4 minutes on each side.
Serve with a tart apple sauce, or as part of an Breakfast Fry, with fried bacon, fried sausage, fried eggs, fried black pudding, fried bread, fried soda bread, etc.
