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 ↓
Casserole of Rice with Tomato Sauce
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 hot water with a little salt, shaking occasionally but do not stir, then drain it.
Add milk mixed with the beaten egg, butter, pepper, and salt, then simmer for five minutes.
If the rice hasn't absorbed all the milk, drain it again.
Shape and bake the rice
Shape the rice around the inner edge of a flat dish, smoothing it into a fence shape.
Brush the rice with the beaten egg yolks.
Bake until firm at 400°F (200°C).
Make the tomato filling and assemble
Drain more than half the juice from the tomatoes.
Season with onion, pepper, salt, and sugar, then stew the tomato mixture for twenty minutes.
Stir in butter and bread crumbs, then cook for an additional three to four minutes to thicken.
Pour into the rice hedge.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the structure of the hedge as its starch sets when cooked and cooled.
- Eggs
- Bind the milk and rice and set firm during baking, holding the shape together.
- Tomatoes
- Provide the main moisture and acidity for the sauce that fills the rice hedge.
- Bread crumbs
- Absorb liquid from the tomatoes and help thicken the sauce.
- Butter
- Adds richness and fat, giving the sauce a smoother texture and flavour.
The step that matters
Drain the rice well and shape it firmly. Excess liquid in the rice makes the wall weak and prone to slumping. Pressing the rice while it is still warm helps the starch hold it in shape as it cools and sets, so the sauce stays inside the hedge.
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.
