Why it works: Rice and tomato 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
- Cold boiled rice
- Forms the bulk of the dish and absorbs the tomato and seasoning flavours as it heats.
- Tomatoes
- Provide moisture and acidity that season the rice and give it its colour.
- Onion
- Softens as it sautés, adding sweetness and savoury depth to the base.
- Butter
- Adds fat to sauté the onion, carrying flavour and helping it brown lightly.

Fit is the average pairing score against rice, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
