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

What each ingredient does

Pea pods
Long simmering extracts their flavour and body into the water, forming the soup base.
Flour
Starch mixed with butter thickens the strained liquid into a smoother, heavier soup.
Butter
Fat binds with the flour to form a paste that carries richness and helps thicken the soup.

The step that matters

Adding the flour and butter paste. Flour must be blended with butter into a smooth paste before adding it to hot soup; loose flour clumps and thickens unevenly, leaving lumps.

Swap the peas

The recipe marks peas as optional. How well each one fits the dish's main ingredients (flour, butter, pepper, bread):

  1. Almondfits better
  2. Chestnutfits better
  3. Beansfits better
  4. Peasthe original

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