Why it works: Pepper and lemon 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 ↓
Sardine Sauce
Ingredients
Directions
Prepare the sauce
Remove the bones from the sardines.
In a saucepan, melt the butter and add water or broth to create a sauce of ordinary thickness.
Add the fish bones, bay leaf, shallot, pepper, nutmeg or mace, and lemon juice to the sauce.
Boil until properly flavored, then strain the sauce.
Finish
Chop the sardines small and add them to the strained sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main fish flavor and body once chopped into the sauce.
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
- Shallot
- Contributes a mild, sweet onion-like aroma as it simmers into the sauce.
- Lemon juice
- Adds acidity that brightens the rich fish flavor.
The step that matters
Boil until properly flavored, then strain. Simmering extracts flavor from the bones, bay leaf and shallot into the liquid. Boiling too briefly leaves the sauce weak, and straining removes solids so the sauce stays smooth before the chopped sardines are added.
Swap the shallot
How well each one fits the dish's main ingredients (butter, pepper, nutmeg, lemon):
- Spinachfits about as well
- Shallotthe original
- Capsicumfits about as well
- Carrotfits about as well
Fit is the average pairing score against butter, pepper, nutmeg, lemon. Candidates are from the same food group and used in at least 100 recipes.
