Why it works: Rice and onion 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 ↓

Cook
Melt the butter in a saucepan and add the chopped onion; cook until the onion begins to color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the bulk of the dish; its starch sets as it absorbs the boiling water.
- Butter
- Adds fat for richness and carries the curry powder's flavor through the rice.
- Curry powder
- Provides the aroma and flavor that define the dish.
- Onion
- Adds savory sweetness as it softens and begins to color in the butter.
The step that matters
Cover and cook rapidly, then reduce heat. Rapid boiling at first brings the water up to temperature, then gentle heat lets the rice absorb the liquid and steam evenly without scorching or leaving it hard in the center.
Swap the onion
How well each one fits the dish's main ingredients (rice, butter, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against rice, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
