Why it works: Butter and milk 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
Open the oysters and boil them for 2 minutes in their own liquor.
Drain the oysters over a colander and strain the liquor.
Make the sauce
Mix ¾ ounce of butter with ¾ ounce of flour to a smooth paste.
Add the oyster liquor and enough milk to make nearly 1 pint.
Stir over heat until it comes to a boil, then remove from heat.
Stir in ½ ounce of butter until melted.
Finish and serve
Remove the gills from the oysters and return them to the sauce to warm.
Do not let the sauce boil after adding the oysters.

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, and are warmed through in it.
- Butter
- Enriches the sauce with fat and adds a rich, smooth mouthfeel.
- Flour
- Thickens the milk and oyster liquor into a smooth sauce when cooked with the butter.
- Milk
- Forms the liquid base of the sauce, giving body and creaminess.
The step that matters
Do not let the sauce boil after adding the oysters. Once the oysters go in, boiling can toughen their proteins and make them rubbery. Gentle warming keeps them tender while the sauce stays smooth.
