Grate raw potatoes and mix with the cooked mashed potatoes. Add salt, pepper and flour. Beat 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 Ulster Fry, with fried bacon, fried sausage, fried eggs, fried black pudding, fried bread, fried soda bread... . An old poem says: . Boxty on the griddle, boxty in the pan, if you can't make boxty, you'll never get a man. . (The accuracy of the poem is uncertain.)
