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

What each ingredient does

Celery
Adds a savory, aromatic flavor that gives the soup its character.
Water or meat liquor
Serves as the cooking liquid that softens the peas and carries flavor through the soup.

The step that matters

Simmer for 45 minutes to thicken. Long, gentle simmering evaporates some water and concentrates the soup, while the broken-down peas release starch that helps it thicken. Too short a simmer leaves it thin, and too hard a boil can scorch the bottom or break the texture.

Swap the mint

How well each one fits the dish's main ingredients (meat, celery, pepper, bread):

  1. Parsleyfits better
  2. Thymefits better
  3. Marjoramfits better
  4. Mintthe original

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