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 ↓
Rice Soup with Tomatoes
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.
Prepare the tomato base
Remove the seeds from the tomatoes and stew them in a little water with the sliced onion.
Rub the mixture through a colander.
Cook the soup
Heat the butter in a pot, then add the tomatoes and rice, cooking for a few minutes while stirring.
Add the stock and bring to a boil for five minutes.
Cover the pot and place it in a preheated 400°F (200°C) oven for one hour.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provides the main body, acidity and fresh tomato flavor of the soup.
- Rice
- Its starch thickens the soup and gives it a creamier body as it cooks.
- Stock
- Serves as the cooking liquid that the rice absorbs and softens in.
- Butter
- Adds fat that carries flavor and rounds out the taste of the tomatoes.
- Onion
- Adds savory sweetness as it softens while stewing with the tomatoes.
The step that matters
Cover the pot before the oven. Covering the pot traps steam so the liquid cannot evaporate too quickly over the long bake. Without a lid, the soup can reduce too far, concentrate unevenly, or scorch on the bottom, while the rice may stay firm.
Swap the tomato
How well each one fits the dish's main ingredients (onion, butter, rice):
- Potatofits better
- Leekfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against onion, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
