Oyster Sauce
Ingredients
Directions
Prepare the oysters
Choose plump and juicy oysters and keep them in their shells until ready to cook.
Strain the oyster liquor.
Place the strained liquor with the oysters in a saucepan.
Bring the mixture to a boil.
Remove from heat.
Strain the contents into a clean basin.
Wash the saucepan with hot water.
Make the sauce
Return the strained liquor to the saucepan.
Add an equal amount of milk.
Rub the butter with the flour in a bowl.
Add the butter‑flour mixture to the saucepan.
Bring the mixture to a boil.
Strain the sauce again to ensure smoothness.
Return the strained sauce to the saucepan.
Finish with oysters
Shave the oysters, removing any gristly parts.
Add only the soft parts to the sauce.
If the oysters are large, cut them in half.
Keep them warm without boiling.

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 pieces that give the sauce its body.
- Oyster liquor
- Adds concentrated briny oyster flavour to the base of the sauce.
- Milk
- Makes the sauce creamy and mellows its sea-like sharpness.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the liquid into a smooth sauce when cooked with the butter.
The step that matters
Keep the sauce warm without boiling. Once the oysters are added, boiling toughens their proteins and makes them rubbery, and it can cause the milk-based sauce to curdle or separate. Gentle heat keeps the oysters tender and the sauce smooth.
