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 ↓
Baked Rice with Tomatoes
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.
Prepare
Boil the rice in water until tender.
Mix the cooked rice with the can of tomatoes.
Add the finely chopped onion, butter, salt, and pepper.
Line a well-buttered dish with bread crumbs.
Bake
Pour the rice mixture into the dish and bake at 350°F (175°C) until golden brown.

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 once cooked.
- Tomatoes
- Add moisture and acidity that flavour the rice as it bakes.
- Onion
- Adds savoury depth and aroma as it softens into the mixture.
- Butter
- Adds richness and helps the top brown during baking.
- Bread crumbs
- Form a crisp lining on the dish that adds texture and helps browning.
The step that matters
Bake until golden brown. The rice mixture is already cooked, so baking mainly sets it and browns the surface. Stopping too early leaves it pale and loose, while baking too long can dry it out.
Swap the onion
How well each one fits the dish's main ingredients (rice, tomato, butter, pepper, bread):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against rice, tomato, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
