Why it works: Chervil and chive match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 370 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the sauce and thicken it into a smooth, rich texture as they set gently with heat.
- Cream
- Adds richness and a silky mouthfeel that softens the sauce's flavor.
- Butter
- Adds fat for a glossy finish and a rounder, silkier texture.
- Velouté sauce
- Serves as the base body of the sauce, providing thickness and structure.
- Fish stock
- Provides concentrated savory flavor once reduced.
The step that matters
Bind the sauce with the egg yolks and cream. Egg yolks thicken by coagulating when heated, but if the sauce boils after they are added they can scramble and turn grainy. Keep the heat low and stir constantly while binding.
Swap the parsley
How well each one fits the dish's main ingredients (fish, sauce, egg, cream, chervil, chive, butter):
- Capersfits better
- Tarragonfits better
- Parsleythe original
- Nutmegfits about as well
Fit is the average pairing score against fish, sauce, egg, cream, chervil, chive, butter. Candidates are from the same food group and used in at least 100 recipes.
