Name: Oyster Sauce
Ingredients: 2 tablespoons flour; 2 tablespoons butter; ¼ teaspoon coarse sea salt; ¼ teaspoon black pepper; 2 slices lemon; ¼ teaspoon ground mace; 1 cup veal stock or good stock; 1 dozen oysters; Grated bread for serving

Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,047 recipes mention both. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Flour and butter 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

Flour: Thickens the stock into a smooth sauce as it cooks.
Butter: Carries the flour and adds richness and body to the sauce.
Oysters: Give the sauce its main briny, savoury flavour as they simmer.
Veal stock: Forms the liquid base that carries the flavour of the sauce.

Fit is the average pairing score against flour, butter, pepper, lemon, veal, oyster, bread. 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).
