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
Choose plump and juicy oysters and keep them in their shells until ready to cook.
Save the oyster liquor and strain it.
Make the sauce
Place the strained liquor in a stew-pan with the oysters and bring the mixture to a boil.
Remove from heat and strain the contents into a clean basin.
Wash the stew-pan with hot water and return the strained liquor to it.
Add the milk and butter, mixed with the flour, and bring the mixture to a boil.
Strain the sauce again into a basin for smoothness, then return it to the sauce-pan.
Finish and serve
Shave the oysters, remove any gristly parts, and add only the soft parts to the sauce.
If the oysters are large, cut them in half.
Keep them warm without boiling.
If you lack enough liquor, add melted butter, cream, or milk mixed with an egg yolk after the sauce is done.

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 soft texture of the stew, releasing briny liquor as they cook.
- Milk
- Adds moisture and creaminess, giving the sauce a smooth, rich body.
- Butter
- Adds fat for richness and a silky mouthfeel to the sauce.
- Flour
- Thickens the milk and butter mixture so the sauce becomes body-rich instead of thin.
The step that matters
Keep the sauce from boiling after the oysters are added. Oysters turn tough and rubbery when overheated, so they should be kept warm just below boiling to stay tender.
