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 ↓
Oyster Fricassee
Ingredients
Directions
In a saucepan, mix the butter and flour over medium heat until a smooth paste forms.
Add the strained oyster liquor and a little water if necessary.
Season with salt, pepper, and nutmeg, then bring to a boil.
Add the oysters and cook until the edges curl.
Remove from heat and stir in the egg yolks, salad oil, vinegar or lemon juice, and chopped parsley.
Serve immediately.

Butter and flour 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
- Butter
- Enriches the sauce and adds richness along with the flour's thickening base.
- Flour
- Thickens the liquor into a smooth sauce when cooked with the butter.
- Egg yolks
- Enrich and thicken the sauce, giving it a smooth, creamy body.
- Oyster liquor
- Supplies the main liquid and briny oyster flavour of the sauce.
- Vinegar or lemon juice
- Adds acidity that brightens the rich, creamy sauce.
The step that matters
Stir the egg yolks in off the heat. Egg yolks thicken by gentle heat and can scramble or curdle if the sauce is too hot when they are added, so they are stirred in after removing it from the heat.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, flour, oyster, pepper, egg, vinegar, parsley):
- Tarragonfits better
- Capersfits about as well
- Dillfits about as well
- Nutmegthe original
Fit is the average pairing score against butter, flour, oyster, pepper, egg, vinegar, parsley. Candidates are from the same food group and used in at least 100 recipes.
