Why it works: Milk and butter 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 the liquor
Choose plump, juicy oysters and do not remove them from their shells until ready to cook.
Save the oyster liquor, strain it, and place it in a stew pan with the oysters.
Bring to a boil, then remove from heat and strain the mixture into a basin.
Wash the stew pan with hot water, then return the strained liquor to it.
Make the sauce
Add milk and butter mixed with flour, then bring to a boil again.
Strain the sauce into a basin to ensure smoothness, then return it to the pan.
Shave the oysters, adding only the soft parts to the sauce, and keep warm without boiling.
If needed, add melted butter, cream, or milk mixed with egg yolk to adjust consistency.
For added flavor, pound half a dozen raw oysters, strain, and stir into the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and, when soft parts are added, body to the sauce.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Flour
- Thickens the milk and liquor into a smooth, cohesive sauce.
- Milk
- Adds body and creaminess, mellowing the briny oyster liquor.
The step that matters
Keep the sauce warm without boiling. Once the oysters and flour-thickened milk are in, boiling can curdle the dairy, toughen the oyster pieces and break the smooth texture the sauce depends on.
