Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Curry of Cold Meat
Ingredients
Directions
Make the sauce
Heat the butter in a pan.
Slice the onion thinly and fry until light brown.
Stir in the flour and curry powder, cooking for about 1 minute.
Slowly add the stock and bring the sauce to a boil.
Skin and slice the tomato, then peel and chop the apple.
Mix the tomato, apple, salt, curry paste, and coconut into the sauce.
Simmer for 1 hour, stirring frequently.
Add the meat and serve
Cut the cold meat into one-inch squares, removing excess fat and skin.
Add the meat to the sauce and heat gently until warmed through, or simmer until tender if underdone.
Serve in a border of rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Provides the main protein and bulk of the dish.
- Flour
- Thickens the sauce when cooked with the butter and curry powder.
- Onion
- Frying until light brown builds sweetness and savoury depth in the base.
- Curry powder
- Supplies the main spice flavour, toasted briefly in the fat to release aroma.
- Apple
- Adds mild sweetness that balances the spices and acidity.
- Tomato
- Adds acidity and body to the sauce.
The step that matters
Simmer the sauce before adding the meat. The sauce must simmer long enough for the flour to thicken fully and the spices and vegetables to soften and blend. Cold meat only needs gentle heating, so adding it too early or boiling it can make it tough and dry.
Swap the apple
How well each one fits the dish's main ingredients (meat, onion, flour, tomato, coconut, butter):
- Avocadofits better

- Cherryfits better
- Applethe original
Fit is the average pairing score against meat, onion, flour, tomato, coconut, butter. Candidates are from the same food group and used in at least 100 recipes.
