Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Hashed Mutton
Ingredients
Directions
Prepare the mutton
Cut the cold mutton into thin slices, ensuring they are free from veins and skin.
Dredge the slices with a little flour and season with pepper and salt.
Cook the hash
In a stewpan, melt a bit of butter and add the mutton slices along with a little gravy.
Heat the mixture until hot, but do not let it boil.
Stir in 1 tablespoon of walnut or mushroom catsup.
Serve
Serve the hash on slices of toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mutton
- Provides the meat that forms the body of the hash.
- Flour
- Dredging coats the slices, helping them brown lightly and thickening the gravy slightly.
- Butter
- Adds richness and helps the slices brown in the stewpan.
- Gravy
- Supplies moisture so the meat stays tender when heated.
- Walnut or mushroom catsup
- Adds a concentrated, savoury tang that deepens the flavour of the sauce.
The step that matters
Heat until hot but do not boil. Boiling toughens cooked meat and can make the thickened gravy separate or turn grainy. Gentle heating warms the mutton through while keeping it tender and the sauce smooth.
Swap the walnut
