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

What each ingredient does

Green peas
Form the main body of the dish and give it its bulk.
Butter
Adds fat and richness, and helps give the peas a smooth coating.
Flour
Thickens the cooking liquid so the peas are coated rather than watery.
Lettuce
Softens as it cooks and adds moisture and a mild sweetness to the peas.

The step that matters

Adding the butter-flour mixture. Flour added directly to hot liquid can clump. Mixing it with butter first coats the flour particles so they disperse evenly and thicken smoothly.

Swap the peas

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

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

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