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 ↓
Brown Fricassee of Oysters
Ingredients
Directions
Prepare
Drain the oysters and remove gills.
Heat oysters in a saucepan until the edges curl.
Make the sauce
In a bowl, rub together the butter and flour.
Gradually add the milk to the butter and flour mixture.
Stir in the onion, bay leaf, Worcestershire sauce, salt, and pepper.
Bring to a boil, then add the oysters.
Serve
Once very hot, remove the bay leaf and serve in a shallow dish.
Garnish with triangular pieces of toast and dust with chopped parsley.

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
- Oysters
- Provide the main ingredient, with a tender texture and briny flavor.
- Butter
- Adds richness and fat, and combines with flour to thicken the sauce.
- Flour
- Thickens the milk into a smooth, creamy sauce with the butter.
- Milk
- Forms the liquid base of the sauce, giving it a creamy body.
- Worcestershire sauce
- Adds savory, tangy depth to the creamy sauce.
The step that matters
Bring to a boil, then add the oysters. Oysters cook quickly and turn tough and rubbery if overcooked. Adding them once the sauce is very hot, and heating only until the edges curl, keeps them tender.
Swap the onion
How well each one fits the dish's main ingredients (oyster, sauce, parsley, butter, milk, pepper, flour):
- Shallotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against oyster, sauce, parsley, butter, milk, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
