Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Oyster Sauce
Ingredients
Directions
Cook the oysters
Stew the oysters in their own liquor for 5 minutes, then add the milk.
When it boils, strain the liquor and return it to the saucepan.
Finish the sauce
Thicken with the flour mixed with cold water, stirring well.
Add the butter and cayenne pepper (if desired), and boil for 1 minute.
Squeeze in the lemon juice, mix well, and pour out.

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 body of the sauce.
- Flour
- Thickens the liquid as its starch swells when heated.
- Butter
- Adds richness and a smooth, glossy mouthfeel.
- Milk or cream
- Adds creaminess and softens the sauce's flavour.
- Lemon juice
- Adds acidity that brightens the rich sauce.
The step that matters
Thickening with the flour mixture. Mixing the flour with cold water first lets it disperse without lumps. Stir it in well while the liquid is hot, because the starch only thickens the sauce fully once it has heated and swelled.
Swap the lemon
How well each one fits the dish's main ingredients (oyster, butter, flour, milk, pepper, nutmeg):
- Lemonthe original
- Figfits about as well
- Raisinfits less well
- Coconutfits less well
Fit is the average pairing score against oyster, butter, flour, milk, pepper, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
