Haggis is a traditional Scottish food made by combining a sheep's heart, liver and lungs with onions, oatmeal, barley, suet, salt and spices and stuffing it into a sheep's stomach. The stuffed stomach is then boiled. You can purchase pre-made haggis online from companies like McKean's, The Black Face Meat Company and Caledonian Kitchen. Once you receive the haggis, you will need to reheat it. Make a meal out of it by serving it with mashed turnips and potatoes.
Wrap the haggis with aluminium foil.
Fill a pot with water. Place it on a burner set to medium heat. Bring the water to a boil.
Add the foil wrapped haggis to the pot of boiling water.
Boil the haggis for 45 minutes to reheat it.
