Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fricasseed Oysters
Ingredients
Directions
Prepare the base
Rinse the oysters in a colander under cold water.
In a saucepan, combine water, parsley, and celery seed; bring to a boil.
Add the milk to the boiling mixture.
Make the custard
Mix flour with a spoonful of cold milk, then beat in the egg yolks and stir into the saucepan.
Stir until the yolks thicken, but do not let it boil.
Cook and serve
Add butter, salt, pepper, and oysters; cook until oysters are fringed and swollen without boiling.
Stir in the rusk, remove from heat, and serve in a warm chafing dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Main ingredient; they swell and firm gently in the warm sauce, becoming the dish's centrepiece.
- Egg yolks
- Thicken the sauce as they set with gentle heat, giving it a smooth, rich body.
- Butter
- Adds fat and richness, giving the sauce a smooth, silky mouthfeel.
- Flour
- Stabilises the custard, helping it thicken smoothly without curdling.
- Milk
- Forms the liquid base of the sauce and adds sweetness and body.
- Double baked rusk
- Crushed and stirred in at the end, it adds body and absorbs excess liquid.
The step that matters
Stir the yolks until thickened, without boiling. Egg yolks set at low heat but scramble if boiled, leaving the sauce grainy and curdled. Keeping the heat gentle and stirring constantly keeps it smooth. The oysters also toughen and shrink if overcooked, so they should only cook until fringed and swollen.
Swap the celery
How well each one fits the dish's main ingredients (oyster, parsley, milk, flour, egg, butter, pepper):
- Nutmegfits better
- Capersfits better
- Thymefits about as well
- Celerythe original
Fit is the average pairing score against oyster, parsley, milk, flour, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
