Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Directions
Prepare
Cut the cold meat into nice pieces and season with salt and pepper.
Place the bones and bits of gristle in a saucepan with cold water and boil gently for 1 to 2 hours.

Add 1 teaspoon of curry powder.
Add 1 cup of tomatoes.
Combine and serve
Add the seasoned meat to the sauce and simmer until heated through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browned in fat, it thickens the broth into a sauce and adds a toasted, nutty flavour.
- Broth
- Forms the liquid base of the sauce, carrying the flavour of the bones and gristle.
- Butter or drippings
- Carries the frying of the flour and onion and adds richness to the sauce.
- Cold meat
- The main protein, gently reheated in the sauce until warmed through.
The step that matters
Browning the flour. Flour must be stirred in hot fat until it turns rich brown. Stopping too early leaves a raw, pasty taste, while scorching gives a bitter flavour and dark specks in the sauce.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (meat, pepper, butter, flour, onion, milk):
- Potatofits better
- Leekfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against meat, pepper, butter, flour, onion, milk. Candidates are from the same food group and used in at least 100 recipes.
