Why it works: Pepper and lime match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 3,491 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Haggis
Ingredients
Directions
Prepare the stomach
Wash the sheep's stomach thoroughly in several waters and scald the inside.
Soak the stomach in lime water or strong salt water.
Make the filling
Boil the heart and liver until they can be grated.
Grate the liver and chop the heart finely.
Mix the grated liver, chopped heart, oatmeal, and suet together, seasoning with pepper and salt.
Stuff and boil
Stuff the mixture into the stomach, sewing it up carefully to exclude air.
Boil the haggis in enough water to cover it for two to three hours, pricking the bag with a needle in several places.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Absorbs liquid and fat and gives the filling its crumbly, binding body.
- Suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Liver
- Contributes a deep, savoury flavour and a soft texture when grated.
- Heart
- Adds meaty body and savoury flavour to the filling.
- Onions
- Add sweetness and aroma to the filling.
The step that matters
Stuffing the stomach without trapping air. Air left inside the stomach can expand during boiling and cause the bag to burst. Packing the filling firmly and sewing the bag closed carefully helps prevent this.
Swap the onion
How well each one fits the dish's main ingredients (liver, pepper, lime):
- Capsicumfits better
- Carrotfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against liver, pepper, lime. Candidates are from the same food group and used in at least 100 recipes.
