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 ↓
Italian Rice
Ingredients
Directions
Melt the butter in an earthenware stewpan.
Add the minced onion and rice, stirring over the heat for a few minutes without browning the onion.
Add the water or stock and reduce.
Stir in the tomato pulp, adding more stock or water if needed.
Continue cooking while stirring until nearly all the moisture is absorbed and the rice is cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Provides the bulk of the dish and absorbs liquid as it cooks, becoming tender and soft.
- Butter
- Adds richness and fat, carrying flavour while the onion and rice cook.
- Tomato pulp
- Adds acidity, colour and savoury flavour to the rice as it cooks down.
- Onion
- Contributes aroma and savoury sweetness as it softens in the butter.
The step that matters
Stirring the onion and rice without browning the onion. Gentle heat and stirring soften the onion and coat the rice in fat, releasing aroma. Browned onion turns bitter and darkens the dish, changing its flavour and colour.
Swap the tomato
How well each one fits the dish's main ingredients (rice, onion, butter):
- Potatofits better
- Leekfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against rice, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
