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

What each ingredient does

Butter
Enriches the sauce and carries flavour, giving it a rich, smooth body.
Flour
Thickens the butter and liquid into a smooth sauce that coats the peas.
Preserved peas
Provide the main body and sweet, earthy flavour of the dish.

The step that matters

Boil the butter-flour mixture until thickened. Flour must be cooked in hot liquid long enough for its starch to swell and thicken the sauce; stopping early leaves a thin sauce with a raw, pasty taste.

Swap the peas

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

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

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