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, then 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, then mix in the flour smoothly.
Strain into the stock or milk and oyster liquor, stirring until the sauce boils.
Let the sauce sit by the fire until the butter rises to the top, then carefully remove it.
Reheat the sauce with the cream, then 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
- Enriches the sauce and adds richness and a smooth, rounded flavor.
- Flour
- Thickens the melted butter and milk or stock into a smooth, cohesive sauce.
- Cream
- Adds richness and body, softening the sauce's texture.
- Oysters
- Provide the main briny, savoury flavor of the sauce.
- Milk or white stock
- Forms the liquid base of the sauce, carrying flavor from the simmered gills.
The step that matters
Stirring the sauce as it comes to a boil. Flour must be fully dispersed in the hot liquid while stirring; otherwise it clumps into lumps instead of thickening the sauce evenly.
