Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main protein; boiling first makes it tender before it joins the gravy.
- Butter
- Carries the curry powder and onion flavour and adds richness to the dish.
- Onion
- Browning in the butter builds sweetness and savoury depth into the gravy.
- Flour
- Thickens the broth into a smooth gravy that coats the mutton.
- Broth from boiled mutton
- Forms the liquid base of the gravy and carries meat flavour.
The step that matters
Stirring the flour into the butter and curry powder. Flour must be cooked and evenly dispersed in the fat before the broth is added; otherwise it clumps and leaves a raw floury taste and lumpy gravy.
