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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh tomatoes
- Provide the main body and tomato flavor of the soup.
- Rice
- Softens as it cooks and adds body to the soup.
- Flour
- Thickens the liquid so the soup becomes smooth and coats the spoon.
- Butter
- Adds fat for richness and a silky mouthfeel.
- Milk
- Adds creaminess and a mellow, rounded flavor to the tomatoes.
- Baking soda
- Neutralizes some of the tomatoes' acidity, softening their sharpness.
The step that matters
Stirring in the milk with the baking soda. Milk can curdle when it meets hot, acidic tomato liquid. Baking soda raises the pH and helps prevent this, so it should be stirred in well before the milk is added. Keep the final boil brief so the soup stays smooth.
Swap the tomato
