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

What each ingredient does

Split peas
Form the body of the soup, thickening it as they break down when boiled.
Onions
Browning in butter builds savory, sweet depth of flavor in the soup.
Carrots
Add natural sweetness and body once cooked and pressed through the sieve.
Turnips
Contribute mild sweetness and body when browned and pureed into the soup.
Butter
Carries flavor and browns the vegetables, adding richness to the soup.

The step that matters

Pressing the mixture through a sieve. Cooked peas and vegetables must be passed through fully to create a smooth texture; leftover lumps or skins make the soup grainy.

Swap the peas

How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, pepper, celery, vinegar):

  1. Beansfits better
  2. Lentilsfits better
  3. Chickpeafits better
  4. Peasthe original

Fit is the average pairing score against onion, carrot, turnip, butter, pepper, celery, vinegar. Candidates are from the same food group and used in at least 100 recipes.
