Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidney beans
- Form the body of the soup and thicken it when pureed through a sieve.
- Brown stock
- Provides the liquid base and savory, beefy flavor for the soup.
- Garlic and onion
- Fried in fat at the start to build aromatic flavor for the soup.
The step that matters
Cook slowly for 1 hour. Gentle simmering lets the beans soften fully and release starch and flavor into the liquid, so the soup sieves smoothly and tastes rounded rather than thin or raw.
Swap the kidney beans
How well each one fits the dish's main ingredients (clove, garlic, onion, thyme, beef, pepper):
- Chickpeafits better
- Black-eyed peafits better
- Lentilsfits better
- Kidney beansthe original
Fit is the average pairing score against clove, garlic, onion, thyme, beef, pepper. Candidates are from the same food group and used in at least 100 recipes.
