Why it works: Pepper and allspice match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 6,395 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Scotch Haggis
Ingredients
Directions
Prepare the organs
Clean the sheep's bag thoroughly with cold and then boiling water.
Parboil the heart, lights, and liver for 1.5 hours, then let them cool.
Mince the cooled organs and the fresh suet very finely.
Fill and cook
Mix the minced ingredients with browned oatmeal, chopped onions, black pepper, allspice, and salt.
Fill the cleaned bag with the mixture, leaving it half full, and add a little of the parboiling liquid.
Sew up the bag and place it in boiling water.
Prick the bag frequently with a large needle to let air escape.
Boil for 3 hours with a plate at the bottom of the pot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Absorbs fat and juices, giving the haggis a crumbly, binding texture.
- Fresh suet
- Adds fat that melts during cooking, keeping the filling moist and rich.
- Sheep's liver
- Contributes savoury depth and body to the minced filling.
The step that matters
Pricking the bag. Steam builds up inside as the filling cooks. Pricking the bag frequently with a large needle lets air escape, so the casing does not burst during the long boil.
Swap the onion
How well each one fits the dish's main ingredients (liver, pepper, allspice):
- Mustardfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against liver, pepper, allspice. Candidates are from the same food group and used in at least 100 recipes.
