In Denmark, traditionally, they are made from minced veal, pork or beef (or a blend of two of these meats); chopped onions; eggs; milk (or water); bread crumbs (or oatmeal or flour); salt; and pepper; then formed into balls and flattened somewhat. They are then pan-fried in pork fat or beef fat, or more commonly in modern times in butter, margarine or even vegetable oil. Another popular variation is "fiskefrikadeller" replacing the meat with fish as the main ingredient and often served with remoulade.
