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

What each ingredient does

Egg yolks
Thicken the buttery pea liquid into a smooth, creamy coating as they set gently with heat.
Lettuce leaves
Add moisture and a soft, sweet body that helps the peas stay tender as they cook.
Butter
Adds richness and a silky mouthfeel, carrying flavor through the peas.
Onions
Contribute aromatic sweetness and savory depth to the cooking liquid.

The step that matters

Do not return to heat for long. Prolonged heat after the egg yolks are added can overcook them, causing curdling and the grayish discoloration the recipe warns about, and it dulls the fresh green color of the peas.

Swap the onion

How well each one fits the dish's main ingredients (peas, butter, chive, lettuce, sugar, egg):

  1. Leekfits better
  2. Shallotfits better
  3. Beetrootfits better
  4. Onionthe original

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