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

What each ingredient does

Green peas
Provide the main flavour and body of the soup.
Flour
Thickens the soup as its starch swells when heated in the liquid.
Butter
Adds fat for a smoother mouthfeel and richer flavour.
Milk
Adds creaminess and moisture to the soup.
Sugar
Adds mild sweetness that rounds out the pea flavour.

The step that matters

Combine the stock with flour and heat through. Flour must be fully mixed into the liquid and heated so its starch thickens the soup and the raw floury taste cooks off. Adding it unmixed can leave lumps.

Swap the peas

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

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

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