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 ↓
Sheep’s Haggis
Ingredients
Directions
Prepare the stomach bags
Wash the stomach bags in cold water.
Plunge the stomach bags into boiling water.
Scrape the stomach bags carefully.
Soak the bags overnight in cold water with a little salt.
Cook the pluck
Wash the pluck.
Place the pluck in a pan of boiling water, letting the windpipe hang over the side to allow impurities to escape.
Boil the pluck for 1.5 hours.
Remove the pluck from the water and let it cool.
Cut away the windpipe and any attached fat or gristle from the pluck.
Make the filling
Grate a quarter of the liver.
Mince the heart, lights, and suet.
Parboil the onions.
Chop the onions.
Dry or toast the oatmeal.
Mix all ingredients thoroughly.
Add black pepper, salt, and ½ cup of the boiling liquor to the mixture.
Fill and cook
Fill the stomach bags slightly more than half full with the mixture.
Sew the stomach bags up.
Place the sewn bags in boiling water.
Boil for 3 hours, pricking the bags occasionally to allow air to escape.
Serve the haggis in a folded napkin on a hot dish without garnish or gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Absorbs the cooking liquor and gives the filling its crumbly, binding body.
- Beef suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Sheep's pluck
- Forms the meaty base of the filling, supplying most of the savoury flavour.
- Onions
- Add sweetness and aroma that balance the richness of the meat and fat.
The step that matters
Filling the stomach bags slightly more than half full. Oatmeal and meat swell as they absorb liquid and cook. Leaving room in the bag prevents it from bursting, and pricking it lets trapped air escape.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper):
- Capsicumfits better
- Tomatofits better
- Carrotfits about as well
- 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.
