Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Their starch softens and thickens the broth as they cook, giving body to the soup.
- Onion
- Softens as it cooks, adding savory aroma and gentle sweetness to the broth.
The step that matters
Boil until the beans fall apart. Dried beans must cook long enough for their starch to fully gelatinize and the skins and interiors to soften. Stopping early leaves the beans firm and the broth thin, while a hard boil can break them up unevenly.
Swap the carrot
The recipe marks carrot as optional. How well each one fits the dish's main ingredients (beans, onion, pepper, turnip):
- Okrafits better
- Leekfits better
- Lettucefits about as well
- Carrotthe original
Fit is the average pairing score against beans, onion, pepper, turnip. Candidates are from the same food group and used in at least 100 recipes.
