Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
Make the base
Melt the butter in a saucepan.
Add the flour and mix well, stirring with a wooden spoon until lightly colored.
Cook the peas

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the base and carries flavor while the flour is cooked into it.
- Flour
- Thickens the butter and peas into a creamy sauce when cooked lightly.
- Peas
- Form the main body of the dish, providing bulk and sweet, vegetal flavor.
- Cream
- Adds richness and a smooth, creamy texture to the finished sauce.
- Egg yolks
- Add richness and body, helping the cream-based sauce turn thick and smooth.
The step that matters
Stir the cream and egg yolk mixture into the peas without cooking further. Egg yolks thicken when heated but can curdle or scramble if overheated. Adding them off the heat or at low heat, without further boiling, keeps the sauce smooth and creamy.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour, pepper, sugar, parsley, lettuce, cream):
- Chestnutfits better
- Almondfits better
- Pistachiofits better
- Peasthe original
Fit is the average pairing score against butter, flour, pepper, sugar, parsley, lettuce, cream. Candidates are from the same food group and used in at least 100 recipes.
