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 ↓
Meat and Rice Casserole
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Grease a baking dish and spread a layer of ground beef or chopped lamb.
Layer and bake
Sprinkle with salt, pepper, grated onion, and tomatoes.
Add a thick layer of cooked rice.
Repeat with a second layer of meat and seasoning, followed by another layer of rice.
Top with a final layer of meat.
Moisten the layers with milk or the reserved rice cooking water.
Cover and bake for 30 minutes, then uncover and bake for an additional 30 minutes to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef or cooked lamb
- Provides the savory meaty base and fat that flavors the layers.
- Cooked rice
- Forms the bulk of the layers and absorbs liquid as the casserole bakes.
- Tomatoes
- Add moisture and acidity that season the meat and rice layers.
- Onion
- Adds aroma and sweetness that flavors the meat layers.
- Milk or rice cooking water
- Moistens the layers so the rice stays tender rather than drying out.
The step that matters
Moistening the layers. Rice dries out as it bakes, so the liquid must reach the layers evenly. Adding it before covering lets the rice steam and soften while the top then browns.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, tomato, rice, milk):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against beef, pepper, tomato, rice, milk. Candidates are from the same food group and used in at least 100 recipes.
