Icelandic hot dog or pylsur is a unique combination of a sausage made from Icelandic free-range lamb, a warm, steamed bun, and toppings such as fried and raw onions, ketchup, sweet brown mustard, and remoulade. This flavorful hot dog was created at Bæjarins Beztu Pylsur (Town's Best), a small hot dog stall which has been preparing them for over 60 years.
