Haggis is a traditional Scottish dish made from sheep's offal, SUET, OATMEAL, and other ingredients. The term 'haggis ingredient' refers to the components used to make the dish. SUET is a type of hard fat found around the kidneys and loins of cattle and sheep, and it is used to give haggis its characteristic texture. OAT is a cereal grain that is commonly used in haggis, and OATMEAL is a type of ground oats that is also used in the dish.
