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

What each ingredient does

Marrowfat peas
Provide the main body and earthy flavor of the soup once pureed.
Butter and flour
Cooked together into a roux that thickens the soup and gives it body.
Milk
Adds richness and a creamy texture to the pureed peas.

The step that matters

Thickening the puree with the roux. Cooking butter and flour together before adding liquid lets the starch swell evenly, which prevents lumps and gives a smooth, consistent thickness.

Swap the peas

How well each one fits the dish's main ingredients (sugar, butter, flour, milk, onion, pepper):

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

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