Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Oyster Sauce
Ingredients
Directions
Prepare
Remove the gills and hard white parts from the oysters.
Cut each oyster into two pieces.
Simmer the gills in the milk or stock to extract the flavor.
Make the sauce
Melt the butter in a saucepan.
Mix the flour into the melted butter smoothly.
Strain the stock or milk and oyster liquor into the sauce, stirring until it boils.
Let the sauce sit by the fire until the butter rises to the top.
Carefully remove the butter that has risen to the top.
Strain the sauce again.
Finish
Heat the sauce with the cream.
Add the oysters and lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the fat base for the sauce and carries rich flavor.
- Flour
- Thickens the liquid as its starch swells when mixed with melted butter and heated.
- Milk or white stock
- Serves as the liquid base, taking on oyster flavor from the simmered gills.
- Cream
- Adds richness and a smoother, silkier mouthfeel to the finished sauce.
- Oysters
- Provide the main flavor and a tender texture in the finished sauce.
The step that matters
Add the oysters and lemon juice. Oysters cook very quickly in warm liquid. Adding them last and only heating until just warmed keeps them tender, because overcooking makes their proteins firm and rubbery.
