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
- Rice
- Its starch absorbs the cooking liquid and swells, giving the dish its body and texture.
- Tomatoes
- They add moisture, color, and a fresh, tangy flavor as they break down into the liquid.
- Onion
- As it softens in the stew, it adds savory aroma and a little sweetness.
- Beef dripping
- Its fat adds richness and carries flavor through the rice.
- Vinegar
- Its acidity brightens the flavor and balances the sweetness of the tomatoes and onion.
The step that matters
Stew for 25 minutes. The rice must absorb the liquid as it cooks. With too little liquid or heat it can stay firm or scorch, and with too much it turns soft and mushy. Keep the pot covered and check that the liquid is being absorbed.
Swap the onion

Fit is the average pairing score against rice, vinegar, tomato, beef, pepper. Candidates are from the same food group and used in at least 100 recipes.
