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 ↓
Scotch Haggis
Ingredients
Directions
Prepare
Clean the haggis bag thoroughly.
Parboil the pluck.
Boil the liver until well cooked.
Grate half of the liver.
Make the filling
Mince the pluck, beef, suet, and onions very finely.
Mix the minced ingredients with dried meal, seasoning with pepper, salt, and mixed spice.
Combine with the gravy.
Fill and cook
Fill the haggis bag, pressing out all the air before sealing it.
If the bag seems thin, wrap it in a cloth to prevent bursting.
Boil the haggis for about two hours if it is large.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meaty body and texture of the filling.
- Suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Dried meal
- Absorbs moisture and binds the minced filling so it holds together.
- Liver
- Adds deep, savoury flavour and richness to the filling.
- Gravy
- Adds moisture and savoury flavour, loosening the mixture.
The step that matters
Pressing out the air before sealing the bag. Trapped air can expand during boiling and cause the bag to burst, so the air should be pressed out before sealing.
