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 ↓
A Fried Curry
Ingredients
Directions
Fry the chicken
Heat butter in a pan and fry the chicken pieces until brown.
Remove the chicken and fry the chopped onions in the same pan with a bit of butter.
Add the fried onions to the chicken along with the curry powder.
Simmer in gravy
Pour in enough gravy to cover the chicken and season with salt.
Cover the pan and bring to a quick boil for a few minutes.
Remove the cover and stir in the lemon juice.
Simmer over low heat until the gravy thickens.
Serve hot.

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 and, browned first, builds savory flavour in the pan.
- Onions
- Soften and sweeten as they fry, adding body and savoury depth to the gravy.
- Curry powder
- Supplies the spice blend and aroma that define the dish's flavour.
- Gravy
- Provides the liquid that cooks the chicken and thickens into a sauce as it simmers.
- Lemon juice
- Adds acidity that brightens the rich, spiced sauce.
The step that matters
Simmer until the gravy thickens. Gravy thickens as its liquid reduces over low heat. Rushing this with high heat can scorch the bottom and leave the sauce thin, so keep it at a gentle simmer and stir.
