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 oysters
Remove the gills from the oysters and set aside the liquor.
Strain the liquor and combine it with the oysters in a saucepan.
Bring the mixture to a boil until the oysters are plump, then remove from heat.
Pour the contents through a sieve into a clean bowl.
Make the sauce
Wash the saucepan with hot water and return the strained liquor to it.
Add milk and the butter–flour mixture, then bring to a boil.
Strain the sauce again for smoothness, then return it to the saucepan.
Shave the oysters, removing any gritty parts, and keep them warm by the fire.
If needed, add melted butter or cream to the sauce.
Season with optional ingredients as desired.

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 body of the sauce; gently cooking them plumps them.
- Oyster liquor
- Adds concentrated briny flavour and liquid that forms the base of the sauce.
- Milk
- Adds creaminess and mild sweetness, softening the sharpness of the brine.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Flour
- Thickens the liquid into a smooth sauce when cooked with the butter.
The step that matters
Bringing the milk and butter–flour mixture to a boil. Flour thickens only when heated enough for its starch to swell, so the sauce must boil briefly. Stirring keeps the flour from clumping into lumps that the final straining must remove.
