Why it works: Onion and beef 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 ↓
Haggis
Ingredients
Directions
Prepare the filling
Grate the liver and mince the suet and onion.
Mix the liver, suet, onion, and dried meal together well.
Season the mixture with coarse sea salt and mixed spices.
Make the broth
Make beef broth using scraps of beef and water from boiling.
Bag and boil
Put the haggis mixture into a bag and add the broth.
Sew up the bag, removing all air before sealing.
If the bag is thin, wrap 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
- Liver
- Adds richness and a dense, savoury body to the filling.
- Suet
- Adds fat that keeps the filling moist and tender as it cooks.
- Dried meal
- Absorbs liquid and gives the filling its firm, crumbly texture.
- Onion
- Adds sweetness and aroma to the filling.
- Beef broth
- Adds moisture so the filling cooks through softly rather than drying out.
The step that matters
Removing all air before sealing the bag. Trapped air can expand during boiling and burst the bag, and pockets of air can leave the filling unevenly cooked. Pressing out air before sealing keeps the haggis compact and intact.
