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 ↓
Rice with Tomatos
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook the rice
Boil the rice in water until soft, shaking occasionally but not stirring.
Drain the rice and mix in milk, beaten egg, butter, pepper, and salt.
Simmer for 5 minutes.
If milk remains, drain again.
Shape the rice into a wall on a dish.
Brush the rice wall with egg yolk.
Bake in the oven at 400°F (200°C) until firm.
Make the tomato filling
In a saucepan, combine tomato conserve, pepper, salt, sugar, and onion.
Stew the tomato mixture for 20 minutes.
Stir in butter and bread crumbs.
Cook the mixture for 3-4 minutes to thicken.
Assemble and serve
Pour the tomato mixture into the center of the rice.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the soft, cohesive base that is shaped into the wall and holds its form when baked.
- Egg
- Binds the rice mixture and, brushed on as yolk, helps the wall brown and set in the oven.
- Milk
- Adds moisture and softness to the rice so it stays tender rather than dry.
- Tomato conserve
- Provides the main body, acidity and flavour of the filling.
- Bread crumbs
- Thicken the tomato filling as it cooks, giving it body.
- Butter
- Adds richness and fat, contributing flavour and a smoother texture.
The step that matters
Shape and bake the rice wall until firm. Rice must be cooked soft but drained well, since excess liquid makes the wall slump. Baking at 400°F sets the egg and firms the surface so the wall holds its shape around the filling.
Swap the onion
How well each one fits the dish's main ingredients (rice, milk, egg, butter, pepper, tomato, sugar):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against rice, milk, egg, butter, pepper, tomato, sugar. Candidates are from the same food group and used in at least 100 recipes.
