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

What each ingredient does

Dried green peas
Break down when boiled to thicken the soup into a smooth body.
Milk or cream
Adds richness and a silky, mellow texture to the finished soup.
Ham bone
Releases savory flavor into the cooking water as it simmers with the peas.
Onions
Build aromatic sweetness and depth as they soften in the soup.

The step that matters

Boil until the peas are perfectly soft. Dried peas must cook fully to break down; undercooked peas stay firm and grainy, so the sieved soup will be coarse. Adding cold water if needed keeps the level sufficient while they soften.

Swap the peas

How well each one fits the dish's main ingredients (milk, parsley, celery, pepper, onion, ham):

  1. Beansfits better
  2. Black-eyed peafits better
  3. Lentilsfits better
  4. Peasthe original

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