Why it works: Anchovy and sauce are a kitchen classic. They rank in the top 2% of all ingredient pairs, and 2,057 recipes mention both. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Oyster Sauce
Ingredients
Directions
Prepare the oysters
Open the oysters and reserve their liquor.
Remove the tough parts from the oysters and stew them with the liquor.
Make the sauce
Add broth or water to the mixture, allowing it to reduce by half.
Strain the mixture and return it to a saucepan with the oysters.
Add anchovy sauce and butter rolled in flour to thicken.
Stir continuously to prevent the butter from curdling.

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 briny, savoury flavour of the sauce.
- Oyster liquor
- Adds concentrated sea flavour and moisture as the base for the sauce.
- Butter
- Adds richness and body, and with flour helps form a smooth, thickened sauce.
- Flour
- Thickens the sauce when cooked with butter, giving it a smooth body.
- Anchovy sauce
- Adds salty, umami depth to the sauce.
The step that matters
Stir continuously when adding the butter. Butter can separate or curdle when it is heated too quickly or left unstirred. Constant stirring keeps the fat emulsified and blended into the thickened liquid, producing a smooth sauce.

Fit is the average pairing score against oyster, anchovy, sauce, butter, flour, pepper. 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).
