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 ↓
Green Peas, Family Style
Ingredients
Directions
Make the sauce base
Melt the butter in a saucepan.
Add the flour and mix well, stirring with a wooden spoon until lightly colored.
Cook the peas
Add the peas and after 2-3 minutes, pour in the boiling water.
Season with salt, pepper, and sugar, then add the parsley and lettuce.
Once the peas are cooked, remove the parsley and lettuce.
Finish with cream
In a bowl, dilute the egg yolks in the cream, then toss with the peas without cooking further.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted fat that carries flavor and gives the base a rich, smooth body.
- Flour
- Thickens the butter and cooking liquid into a light, cohesive sauce.
- Peas
- Main vegetable that gives the dish its body, color and sweet flavor.
- Egg yolks
- Enrich the cream and thicken the sauce gently when tossed with warm peas.
- Cream
- Adds fat and richness, giving the finished peas a smooth, velvety texture.
The step that matters
Toss the egg yolk and cream mixture with the peas without cooking further. Egg yolks thicken when heated, so if they are cooked too long or too hot they can curdle or turn grainy. Tossing them into warm peas off the heat lets them thicken gently into a smooth coating.
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.
