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):
- Leekfits better
- Shallotfits better
- Beetrootfits better
- 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.
