    These mashed potato dumplings, or Kopytka, are called “little hooves” in Polish because they come out shaped just so. Use mashed potato that doesn’t have butter or milk added for best results. They taste very similar to the Italian gnocchi and taste great with buttered bread crumbs or extra pan sauce.
