Why it works: Beans and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,443 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown beans
- Form the main body of the soup; sieving them thickens it and gives a smooth texture.
- Onions
- Soften and turn sweet as they cook, adding depth to the soup's aroma.
- Carrots
- Soften and add natural sweetness and body to the soup.
- Flour
- Starch swells when mixed with liquid and boiled, thickening the soup.
- Milk powder
- Adds milk solids for a richer, creamier body and flavour.
The step that matters
Adding the flour paste. Flour added without first being smoothed in cold water forms lumps that will not disperse. Stirring quickly as the soup comes to the boil lets the starch disperse and swell evenly, thickening the soup smoothly.
Swap the onion
How well each one fits the dish's main ingredients (beans, carrot, flour, milk powder, milk, pepper, ketchup):
- Capsicumfits better
- Potatofits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against beans, carrot, flour, milk powder, milk, pepper, ketchup. Candidates are from the same food group and used in at least 100 recipes.
