Cut up potatoes into French fries. Drop them into a pot of boiling water. As soon as water comes back to a boil, remove the potatoes and place them in cold water. When potatoes are cooled, drain them thoroughly and place on a cookie sheet to freeze. After they are frozen, break the potato sticks apart and pack them in freezer bags. Remove as many as needed at one time. Drop in hot fat and fry until golden brown. These keep and cook beautifully.
