Why it works: Parsley and pepper 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 sauce
Melt the butter in a saucepan over medium heat.
Add the flour and stir until blended.
Combine and serve
Stir in the chicken and cream, and heat the mixture over hot water or in a double boiler.
Once heated, add the yolks of the eggs, pressed and smoothed with a little cream.
Stir in the chopped egg whites and bring the mixture to a boil.
Season with salt and pepper, then serve.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked chicken
- Forms the main body of the dish and carries the creamy sauce.
- Butter
- Enriches the sauce and carries flavour when melted with the flour.
- Flour
- Thickens the butter and cream into a smooth, cohesive sauce.
- Cream
- Adds moisture and richness, giving the sauce a silky texture.
- Hard-boiled eggs
- Yolks enrich and thicken the sauce while chopped whites add body.
The step that matters
Adding the egg yolks. Egg yolks thicken when heated, but if the mixture is too hot they can curdle and turn grainy. Pressing them smooth with cream and adding them over gentle heat helps keep the sauce creamy.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, egg, flour, butter, cream, pepper):
- Nutmegfits about as well
- Tarragonfits about as well
- Parsleythe original
- Turmericfits about as well
Fit is the average pairing score against chicken, egg, flour, butter, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
