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, absorbing the water and butter to become tender.
- Butter
- Adds fat and richness, carrying the curry flavour through the grains.
- Curry powder
- Supplies the dish's main spiced aroma and flavour.
- Boiling water
- Provides the liquid that the rice absorbs as it cooks.
- Onion
- Adds savoury sweetness and aroma as it softens in the butter.
The step that matters
Cover the stewpan and keep the heat low. Once the water is added and the pan is covered, the rice cooks by absorbing its liquid. Rapid boiling followed by low heat lets the grains absorb the water evenly and become tender without scorching on the bottom.
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.
