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 ↓
Fricasseed Oysters
Ingredients
Directions
Prepare the oysters
Strain the oysters and reserve the liquor.
Boil the oyster liquor with parsley, onion, pepper, and salt to taste.
Add the oysters and bring to a boil.
Thicken and finish
In a separate bowl, mix the butter and flour to form a paste.
Stir the paste into the boiling oyster mixture to thicken.
In another pot, boil the milk and whisk in the egg yolks.
Pour the hot milk mixture into a serving tureen and add the oysters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Main ingredient providing the dish's core flavor and texture.
- Butter
- Adds richness and fat, carrying flavor through the sauce.
- All-purpose flour
- Thickens the liquid into a light, smooth sauce when cooked with butter.
- Milk
- Forms the creamy base of the sauce and adds mild sweetness.
- Egg yolks
- Enrich and thicken the milk, giving the sauce body and a silky texture.
- Oyster liquor
- Supplies briny flavor and moisture to the broth.
The step that matters
Whisking the egg yolks into the hot milk. If the milk is too hot or added too quickly, the egg yolks can scramble and curdle instead of thickening the sauce smoothly. Adding yolks gradually and keeping the heat moderate helps them thicken evenly.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (oyster, butter, flour, milk, egg, parsley, pepper):
- Shallotfits better
- Potatofits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against oyster, butter, flour, milk, egg, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
