Peel potatoes and grate on fine grater; add to grated onion and the egg and seasoning. Mix well. Heat a tablespoonful or so of bacon fat in a large skillet. When fat is sizzling, drop batter by large spoonfuls. Brown well on both sides. (Serve at once with hot homemade applesauce or stewed apples. This makes a good main dish meal on winter days.)
