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 Pilau
Ingredients
Directions
Make the pilaf
Fry the sliced onions in 2 oz. (¼ cup) of nut butter until soft.
Add the tomato purée and vegetable stock, flavored with Marmite, and bring to a boil.
Skim the surface, then add the well-washed rice.
Cook gently until the liquid is almost absorbed.
Finish and serve
Melt the remaining nut butter in a stewpan.
When hot, add the rice and stir for a few minutes.
Cover the pan and let it sit on the stove for about 15 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the bulk of the dish and absorbs the stock and tomato flavor as it cooks.
- Nut butter
- Adds richness and fat, carrying flavor and helping the rice grains stay separate.
- Tomato purée
- Provides acidity, color and savory tomato flavor to the cooking liquid.
- Vegetable stock
- Supplies the liquid the rice absorbs, becoming the main source of seasoning.
- Onions
- Soften and sweeten when fried, building a base flavor for the dish.
The step that matters
Cook gently until the liquid is almost absorbed. Rice cooked too hard can boil dry or scorch on the bottom before the grains are tender. Gentle heat lets the liquid absorb evenly and the grains swell without breaking.
Swap the tomato
How well each one fits the dish's main ingredients (onion, butter, rice):
- Potatofits better
- Leekfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against onion, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
