text: Haggis is a tradtional Scottish dish containing sheep's offal (heart, liver and lungs), minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and traditionally simmered in the animal's stomach for approximately three hours (although nowadays haggis tends to be simmered in a casing rather than the stomach).
