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

What each ingredient does

French beans
Form the body of the soup and thicken it as they break down during long cooking.
Potatoes
Add starch that softens the broth and gives the soup body.
Celery
Adds savory aroma and mild flavor to the broth.

The step that matters

Simmer until the vegetables are tender. Potatoes and celery need enough time in the hot liquid for starch to fully soften. Adding them too early or stopping too soon leaves a firm, uneven texture.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (beans, celery, potato, caraway):

  1. Carrotfits better
  2. Beetrootfits better
  3. Chivefits better
  4. Onionthe original

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