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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the bulk of the dish; parboiling makes it tender enough to eat.
- Onions
- Soften and sweeten when fried, forming the base of the curry.
- Drippings
- Carry the heat and add richness when frying the onions.
- Curry powder
- Adds the spiced aroma and flavour that defines the dish.
- Rice
- Absorbs liquid and provides a neutral starch to accompany the curry.
The step that matters
Parboiling the tripe until tender. Tripe is tough and must be cooked long enough, about an hour here, for the connective tissue to soften. Stopping early leaves it chewy, and the later fifteen-minute simmer in the curry will not make up for it.
Swap the onion
How well each one fits the dish's main ingredients (rice, pepper, vinegar):
- Capsicumfits better
- Cucumberfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against rice, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
