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
Prepare the base
Cream the butter in a bowl.
Add the flour and beat together until smooth.
Make the sauce
Cook the oysters in their own liquor until they boil.
Skim out the oysters and add enough water to the liquor to make 1 pint.
Combine the liquor with the butter and flour mixture and cook until it thickens.
Add the oysters back in and season with salt, pepper, and cayenne.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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
- Enriches the sauce with fat, giving it a rich, smooth mouthfeel.
- Flour
- Thickens the liquor and butter mixture so the sauce becomes smooth and coats the oysters.
- Oysters
- Provide the main flavour and the sauce's briny, savoury character.
- Lemon juice
- Adds acidity that brightens the rich butter and briny oyster flavour.
The step that matters
Combine the liquor with the butter and flour mixture and cook until it thickens. Flour thickens only when the liquid is heated enough for its starch to swell. Adding the liquor cold or stopping early leaves a thin, pasty sauce, and overcooking can break it down.
