Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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 body of the dish and absorbs the curry flavour as it simmers.
- Flour
- Thickens the stock into a smooth sauce as it cooks.
- Curry powder
- Supplies the dominant spice aroma and warm flavour of the dish.
- Onion
- Builds a sweet, savoury base for the sauce when cooked gently.
- Apple
- Adds a little natural sweetness that softens the sharpness of the curry spices.
The step that matters
Stir in the flour before adding the stock. Flour must be mixed evenly into the fat and spices so it does not form lumps when liquid is added. Stirring constantly as the stock goes in helps the starch disperse and thicken the sauce smoothly.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (meat, onion, butter, flour, lemon):
- Avocadofits better
- Limefits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against meat, onion, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
