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
- Steak or veal cutlets
- Forms the main body of the dish and becomes tender during slow simmering.
- Onions
- Browning in butter builds sweetness and savoury depth that supports the curry sauce.
- Apple
- Adds natural sweetness and body that softens into the sauce as it cooks.
- Curry powder
- Provides the spiced aroma and flavour that defines the dish.
- Flour
- Coats the meat and thickens the liquid into a sauce.
The step that matters
Fry the meat quickly. Searing the coated meat briefly browns its surface and builds flavour. Frying too long toughens the meat before the slow simmer, and the flour coating can scorch.
Swap the apple
How well each one fits the dish's main ingredients (veal, butter, onion, flour, lemon):
- Avocadofits better
- Limefits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against veal, butter, onion, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
