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 ↓
Tomato Cream Soup
Ingredients
Directions
Run one quart tomatoes through a flour sifter.
Add one quart water, one saltspoon salt, and one-half cup rice.

Add half cup butter in which two tablespoons flour have been creamed.
Nutrition, whole recipe (rough)

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and tangy flavor of the soup.
- Rice
- Cooks down during boiling to thicken the soup slightly.
- Milk
- Adds creaminess and mild sweetness to the tomato base.
- Butter
- Adds richness and a smooth, rounded mouthfeel.
- Flour
- Thickens the butter and softens the soup's texture when creamed in.
The step that matters
Add one teaspoon soda, then skim.. Soda reacts with the acidic tomatoes and can foam up or change color and flavor. Adding it before the milk lets the reaction settle and lets you skim off the foam before the dairy goes in.
Swap the tomato
How well each one fits the dish's main ingredients (flour, rice, milk, butter):
- Potatofits better
- Leekfits better
- Arrowrootfits better
- Tomatothe original
Fit is the average pairing score against flour, rice, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
