Why it works: Oyster and anchovy work together. They rank in the top 8% of all ingredient pairs, and 603 recipes mention both. Both carry decanal, which smells soap, orange peel. The science ↓
Oyster Sauce is Made Thus
Ingredients
Directions
Prepare the oysters
Simmer the oysters until plump, then strain the liquor through a sieve.
Wash the oysters clean and remove the gills.
Place the oysters in a saucepan and pour the liquor over them, avoiding the sediment.
Make the sauce
Add the mace, lemon, anchovy liquor, and horseradish.
Mix in the butter rolled in flour and gently boil for 10 minutes.
Remove the horseradish, mace, and lemon.
Squeeze the lemon juice into the sauce, mix well, and serve in boats or bowls.

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 body and savoury flavour of the sauce.
- Butter rolled in flour
- Thickens the sauce as the flour starch cooks and gives it a smooth, rich body.
- Anchovy liquor
- Adds a salty, savoury depth that rounds out the oyster flavour.
- Lemon
- Adds acidity that brightens the rich butter and oyster flavours.
- Horseradish
- Adds a sharp, pungent aroma that is removed before serving.
The step that matters
Gently boil the sauce after adding the butter and flour. Flour needs to simmer long enough for its starch to swell and thicken the sauce, but a hard boil can break the butter and make the oysters tough.

Fit is the average pairing score against oyster, lemon, anchovy, horseradish, butter, flour. 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).
