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 ↓
Another Way to Make Haggis
Ingredients
Directions
Prepare the pluck
Thoroughly cleanse and parboil the pluck; save ½ pint of the liquor.
Make the filling
Mince the pluck very small with the beef steak, beef fat, and onions.
Season the mixture with pepper and coarse sea salt.
Add the toasted oatmeal and mix well with the reserved liquor and catsup.
Boil
Put the mixture into a bag.
Prick the bag with a fork.
Boil for 3.5 hours.
If desired, boil the haggis in a jar tied over instead of in a bag.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Provides the main meaty body and chew of the filling.
- Beef fat
- Adds moisture and richness, keeping the filling from drying out during boiling.
- Oatmeal
- Absorbs liquid and binds the minced filling into a firm, sliceable texture.
- Onions
- Add sweetness and savoury depth as they soften in the mixture.
- Catsup
- Adds acidity and sweet tang that balances the rich meat and fat.
The step that matters
Prick the bag with a fork. Boiling a sealed bag of meat and fat can cause pressure to build and burst it. Pricking vents steam so the bag stays intact during the long boil.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (beef, pepper):
- Capsicumbetter flavor fit
- Tomatobetter flavor fit
- Carrotabout as good a flavor fit
- Onionthe original
Fit is the average pairing score against beef, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
