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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Fried until light brown, they build the sweet, savoury base of the curry.
- Kidney beans
- Provide the main body and texture of the curry as they soften during slow simmering.
- Strained tomatoes
- Add liquid and acidity that help form the sauce around the beans.
- Butter
- Adds richness and fat that carries the curry flavour.
- Raisins
- Add gentle sweetness that balances the curry spices.
The step that matters
Slow boil for 2 hours. Simmering gently for a long time lets the kidney beans soften fully and the sauce thicken and blend. Boiling too hard can break up the beans and scorch the bottom of the pan, so keep the heat low and check the water level.
