Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 17,451 recipes mention both. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Oyster Sauce
Ingredients
Directions
Make the sauce
In a stewpan, melt the butter with the flour.
In another stewpan, combine the oysters, their gills, and liquor.
Add the milk, salt, cayenne, cloves, mace, and peppercorns to the butter and flour mixture.
Place over heat, stirring constantly, and boil for 10 minutes.
Stir in the essence of anchovies and Harvey sauce.
Finish and serve
Pass the sauce through a fine sieve over the oysters.
Heat the mixture without boiling and serve hot.

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
- Butter
- Forms the fat base with flour, carrying flavour and giving the sauce richness.
- Flour
- Thickens the sauce as its starch swells when heated in the butter and milk.
- Oysters
- Supply the main briny, savoury flavour that defines the sauce.
- Milk
- Forms the liquid body of the sauce and adds a creamy texture.
- Essence of anchovies
- Adds concentrated savoury depth to the sauce.
The step that matters
Boil with constant stirring. Stirring while the flour-thickened milk comes to a boil keeps the starch dispersed, preventing lumps and scorching on the base of the pan. Boiling also cooks the starch fully so the sauce thickens properly.

- Macethe original
Fit is the average pairing score against butter, flour, oyster, milk, pepper, clove, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
