Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Haricot beans
Provide the main body and starch that thicken the soup as they soften.
Bacon
Adds fat and savory, smoky flavor that carries through the broth.
Onion
Adds aromatic sweetness and depth as it softens in the broth.

The step that matters

Boil until the beans and bacon are fully cooked. Dried beans hold firm until their starch has gelatinized with enough sustained heat and time. Stopping early leaves them chalky and grainy, so keep the soup simmering until they are tender throughout.

Swap the onion

How well each one fits the dish's main ingredients (beans, clove, pepper):

  1. Capsicumfits better
  2. Carrotfits better
  3. Sweet potatofits better
  4. Onionthe original

Fit is the average pairing score against beans, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
