Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,047 recipes mention both. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Blanch the oysters
Place the oysters and their liquor in a small saucepan.
Heat the saucepan until it boils to blanch the oysters.
Remove the saucepan from heat as soon as it boils.
Strain the oyster liquor into a basin.
Remove the oysters from the saucepan and place them on a plate.
Remove the gills and hard parts from the oysters, leaving only the soft part.
Make the sauce
Combine the butter and flour in a stewpan, mixing well with a wooden spoon.
Add the strained oyster liquor to the stewpan.
Stir until it boils and thickens.
Stir in the cream.
Bring to a boil again.
Remove the stewpan from heat.
Place the stewpan on a paper on the table.
Add the lemon juice and a few grains of Cayenne pepper to taste.
Finish with oysters
Cut the trimmed oysters into small pieces.
Mix them into the stewpan.

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely 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 flavour and the soft texture of the sauce's added pieces.
- Oyster liquor
- Adds concentrated briny oyster flavour and liquid to the sauce base.
- Butter
- Adds fat and richness, and carries flavour through the sauce.
- Flour
- Thickens the liquor and butter into a smooth, stable sauce.
- Cream
- Adds richness and a smoother, silkier mouthfeel.
- Lemon juice
- Adds acidity that brightens the rich, briny flavours.
The step that matters
Stir the sauce until it boils and thickens. Flour must be cooked while the liquid comes to a boil so it swells and sets the sauce. Stopping early leaves a floury, thin sauce, and overheating after the cream is added can cause it to separate.
