Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,122 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oyster Sauce for Entrees
Ingredients
Directions
Prepare the sauce base
Blanch the oysters in their own liquor and set aside.
In a saucepan, melt the butter and stir in the flour to make a white roux.
Add the onions, mushrooms, parsley, and scallions to the roux.
Make and finish the sauce
Moisten the mixture with the oyster liquor and consommé.
Cook over medium heat until reduced.
Stir in the cream and season with salt and pepper.
Let the sauce thicken, then strain it through a sieve.
Add the oysters to the sauce and serve with fowl, turkey, or chicken.
If serving with fish, add essence of anchovies.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main seafood flavor and tender bite in the finished sauce.
- Butter
- Carries flavor and, with the flour, forms the base of the roux.
- All-purpose flour
- Thickens the sauce when cooked with butter into a roux.
- Onions
- Add savory sweetness and aromatic depth as they soften in the roux.
- Heavy cream
- Adds richness and a smooth, silky body to the reduced sauce.
- Consommé
- Supplies the liquid base and savory meaty flavor of the sauce.
The step that matters
Let the sauce thicken, then strain it through a sieve. Flour thickens the sauce only as it simmers and reduces, so the sauce should be cooked long enough before straining to remove the onion and herb solids and leave a smooth texture.

Fit is the average pairing score against oyster, butter, flour, mushroom, parsley, cream, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
