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
- Onions
- Browned in butter to build a sweet, savory base for the soup.
- Green peppers
- Browned with the onions to add aroma and a slightly sharp, vegetal flavor.
- Tripe or calf brains
- Provides the rich, tender meat that gives the soup its body.
- Raw rice
- Releases starch as it cooks, thickening the broth and adding body.
- Tomatoes
- Add acidity and fresh flavor, brightening the broth.
The step that matters
Browning the onions and green peppers. Browning caramelizes their natural sugars and builds deep flavor for the whole soup. Pale, under-browned vegetables leave the broth tasting flat, so color them well before adding liquid.
