Why it works: Chicken and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main protein, which becomes tender and firm as it cooks through.
- Butter
- Carries heat for frying and helps the chicken brown to a golden colour.
- Onions
- Soften and turn sweet as they cook, building body into the sauce.
- Curry powder
- Supplies the spice blend that gives the dish its characteristic aroma and flavour.
The step that matters
Frying the chicken until golden brown. Browning through the Maillard reaction creates deep savoury flavour on the surface of the meat. Pale, under-browned pieces will taste flat in the finished curry, so let them colour before moving on.
Swap the onion
How well each one fits the dish's main ingredients (chicken, butter):
- Potatofits better
- Onionthe original
- Leekfits less well
- Tomatofits less well
Fit is the average pairing score against chicken, butter. Candidates are from the same food group and used in at least 100 recipes.
