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 supply its sweet, fresh flavor.
Butter rolled in flour
Thickens the cooking liquid into a light, smooth coating around the peas.
Egg yolks
Enrich and thicken the liquid as they warm, adding richness and body.
Onions
Build a savory aromatic base that flavors the peas as they cook.
Sweet herbs
Add fresh, herbal aroma that brightens the sweetness of the peas.
Sugar
Adds sweetness that balances the savory onions and salt.

The step that matters

Adding the beaten egg yolks. Egg yolks scramble and curdle if the mixture gets too hot. Stir them in off the heat or at a gentle warmth, keep stirring, and only warm until the mixture thickens slightly and looks smooth.
