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 Soup
Ingredients
Directions
Cook the rice
Boil the rice in 5 cups of water with the butter, salt, and pepper until tender.
Finish the soup
Once the rice is soft, add the tomato juice and cheese.
Stir until the soup boils and the cheese is dissolved.
If too much water has evaporated, add a little more.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Its starch softens and thickens the broth as it cooks, giving the soup body.
- Tomato juice
- Adds liquid, acidity and tomato flavor to the soup.
- Cheese
- Melts into the hot soup, adding richness and a creamy texture.
- Butter
- Adds fat, which carries flavor and rounds out the broth.
The step that matters
Stir until the cheese is dissolved. Cheese stirred into very hot liquid can turn grainy or stringy if it overheats or separates. Stirring gently while it melts keeps the soup smooth.
Swap the tomato
How well each one fits the dish's main ingredients (rice, cheese, butter, pepper):
- Capsicumfits about as well
- Potatofits about as well
- Tomatothe original
- Asparagusfits about as well
Fit is the average pairing score against rice, cheese, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
