Why it works: Tomato and rice 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 ↓
Tomato Pilaff
Ingredients
Directions
In a pot, cook together the tomato, onion, stock or gravy, salt, and pepper until boiling.
Add the rice and toss lightly until the liquid is absorbed.
Melt the butter and pour it over the rice.
Cover and set on the back of the stove to steam for about 20 minutes.
Remove the cover, shake the pot to separate the rice kernels, and cover with a towel until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the body of the dish as its starches absorb liquid and soften during steaming.
- Butter
- Adds richness and a smooth mouthfeel, coating the rice grains so they separate more easily.
- Stewed tomato
- Provides acidity, color, and tomato flavor that the rice absorbs as it cooks.
- Stock or gravy
- Supplies the cooking liquid that the rice absorbs, adding savory depth.
The step that matters
Toss the rice until the liquid is absorbed. Rice must absorb the liquid before steaming; if liquid remains, the grains turn soggy, and if it is fully absorbed too early, the rice may scorch or cook unevenly.
