A hot dog (also known as a frankfurter, frank, wiener, or weenie) is a moist sausage of soft, even texture and flavor, often made from advanced meat recovery or meat slurry. Most types are fully cooked, cured or smoked. When served, it is usually hot, and is placed in a special purpose soft, sliced hot dog bun, although it is possible for them to be eaten alone. It may be garnished with mustard, ketchup, onion, mayonnaise, relish, cheese, chili or sauerkraut. The flavor can be similar to a range of meat products from bland bologna to spicy German bockwurst varieties. Hot dogs made from a range of meats are on the market, but Kosher or Halal hot dogs must be made from beef, chicken or turkey. Vegetarian hot dogs made from meat analogue are available.
