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 oysters from their shells and place them in a saucepan.
Strain the oyster liquor.
Add the strained liquor to the oysters.
When the oysters begin to boil, remove them from heat.

Wash the saucepan with hot water.
Make the sauce
Add the strained liquor and milk to the saucepan.
In a separate bowl, mix the butter with the flour until smooth.

Strain the mixture back into the saucepan.
Add the oysters back to the sauce.
Heat gently before serving.

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.
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 texture of the sauce once gently cooked.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the liquid into a smooth sauce when cooked with the butter.
- Milk
- Adds body and mildness, softening the briny oyster liquor.
The step that matters
Mixing the butter and flour into the liquid. If the butter-flour mixture is added without being smooth, lumps of raw flour can form. Bringing the mixture to a boil cooks out the raw starch taste and lets the flour thicken the sauce evenly.
