Why it works: Tomato and rice match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,065 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Indian Curry
Ingredients
Directions
Make the curry base
Heat oil in a frying pan and fry the sliced onions until light brown.
Add butter, curry powder, and a little more oil, then cook with the onions for 10 minutes.
Simmer the curry
Mix in kidney beans, strained tomatoes, raisins, chutney, and water if needed.
Allow to boil slowly for 2 hours.
Cook the rice and serve
Cook rice for 20 minutes until kernels are separate.
Serve the curry in the center of a platter with rice around it and garnish with toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sliced onions
- Soften and brown to build the sweet, savoury base of the curry.
- Curry powder
- Supplies the main spice flavour and aroma as it is fried in fat.
- Kidney beans
- Provide the bulk, body and protein of the dish.
- Strained tomatoes
- Add acidity and liquid that thickens into the sauce as it simmers.
- Seeded raisins
- Add sweetness that balances the spices and acidity.
The step that matters
Simmer slowly for 2 hours. A gentle, slow boil lets the sauce reduce and the flavours meld while the beans soften evenly. Boiling too hard can break down the beans and scorch the sauce on the bottom of the pan.
Swap the raisin
How well each one fits the dish's main ingredients (onion, butter, kidney beans, tomato, rice):
- Avocadofits better
- Coconutfits better
- Cherryfits better
- Raisinthe original
Fit is the average pairing score against onion, butter, kidney beans, tomato, rice. Candidates are from the same food group and used in at least 100 recipes.
