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
- Raw rice
- Starch that softens and thickens the liquid into a creamy, risotto-like texture.
- Milk
- Liquid that cooks the rice and adds richness and creaminess to the dish.
- Onions
- Aromatic base that adds sweetness and savory depth as they soften.
- Tomatoes
- Add acidity, moisture and fresh flavor that blends into the rice as it cooks.
- Finely grated cheese
- Adds fat, savory flavor and creaminess when stirred in at the end.
The step that matters
Adding milk while boiling. Rice absorbs liquid as it cooks, so it can stick or scorch if the pan dries out. Adding milk as needed keeps the starch loosening gradually for a creamy result.
Swap the onion
How well each one fits the dish's main ingredients (milk, rice, tomato, pepper, cheese):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against milk, rice, tomato, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
