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 ↓
Savory Rice
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook and brown the rice
Add 2 teaspoons of salt to 3 quarts of boiling water in a large pot and cook the rice until soft but not broken.
Drain and dry the rice.
Melt butter in a saucepan.
Brown the onion in the melted butter.
Remove the onion from the saucepan.
Add the rice to the saucepan and stir until browned.
Prepare the tomatoes
Heat the tomatoes in another pan for 20 minutes.
Rub the heated tomatoes smooth.
Season the tomatoes with salt and pepper.
Stir the seasoned tomatoes into the rice.
Bake
Sprinkle cheese over the mixture.
Transfer the mixture to a buttered baking dish.
Cover with buttered crumbs.
Brown in the oven at 350°F (175°C).

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 gives it a soft, starchy body.
- Tomato pulp
- Adds moisture, acidity and a fresh tomato flavour to the rice.
- Butter
- Adds richness and helps the rice and crumbs brown.
- Cheese
- Melts into the mixture and adds savoury flavour and browning.
The step that matters
Browning the rice in butter. Rice must be drained and dried before it hits the butter, since surface moisture steams it instead of letting it brown. Stirring it in the hot fat gives browned, nutty flavour that carries into the finished dish.
Swap the onion
How well each one fits the dish's main ingredients (rice, butter, tomato, pepper, cheese):
- Capsicumfits better
- Potatofits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against rice, butter, tomato, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
