Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
A Good Scotch Haggis
Ingredients
Directions
Prepare
Clean the haggis bag thoroughly.
Parboil the draught (sheep's stomach).
Boil the liver well and grate it.
Dry the meal in front of the fire.
Mince the draught and the beef finely.
Make beef stock using scraps and water from boiling the draught.
Make the filling
Mix the minced meats, grated liver, suet, onions, and dried meal together.
Season the mixture with salt and mixed spices.
Fill and cook
Put the haggis mixture into the bag along with the stock.
Sew up the bag, ensuring to remove all air before sealing.
If the bag is thin, place it in a cloth.
Boil the haggis for at least 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried meal (oatmeal)
- Absorbs liquid and gives the filling its body and a grainy, crumbly texture.
- Suet
- Adds fat that keeps the filling moist and rich during long boiling.
- Liver
- Contributes savory depth and a firmer, rich texture to the filling.
- Beef
- Provides meaty flavor and substance to the filling.
- Onions
- Add sweetness and aromatic flavor to the filling as they cook.
- Beef stock
- Adds moisture and savory beef flavor that the meal absorbs during cooking.
The step that matters
Remove all air before sealing the bag. Trapped air can expand during boiling and cause the bag to burst, and it can leave pockets in the filling. Pressing out air before sewing keeps the haggis intact and evenly cooked.
