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 ↓
Fricassee of Oyster
Ingredients
Directions
Prepare the oysters
Drain the oysters and rinse them with cold water, then drain again.
Place the oysters in a bowl and keep them in a cool place until ready to use.
Make the sauce
In a chafing dish, combine 2 tablespoons of butter and 2 tablespoons of flour, rubbing them together.
Light the lamp and stir the mixture for a moment.
Add 1 cup of milk and stir constantly until the sauce is smooth.
Cook and serve
Add the oysters and stir until the edges curl.
Mix in ½ teaspoon of salt, a few shakes of cayenne, the beaten egg yolks, and parsley, then stir for a moment.
Turn off the heat and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Main ingredient; their briny flavour is the core of the dish and they curl as they cook.
- Egg yolks
- Beaten into the hot sauce to thicken it and enrich its texture.
- Flour
- Cooked with butter to form a roux that thickens the milk into a sauce.
- Milk
- Forms the liquid base of the sauce, giving it body and a creamy texture.
- Butter
- Enriches the sauce with fat and flavour and forms the base of the roux.
The step that matters
Adding the egg yolks. Egg yolks thicken when heated but can scramble into lumps if they meet a very hot sauce. Keep the heat low and stir steadily so the sauce stays smooth and creamy.
Swap the parsley
How well each one fits the dish's main ingredients (oyster, egg, butter, sauce, flour, milk, pepper):
- Nutmegfits about as well
- Capersfits about as well
- Parsleythe original
- Tarragonfits about as well
Fit is the average pairing score against oyster, egg, butter, sauce, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
