Why it works: Capers and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 372 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sardine Salad
Ingredients
Directions
Assemble the salad
Remove skin and bones from the cold dressed fish and tear it into flakes.
Layer the fish in the center of a dish and sprinkle with minced gherkins and bruised capers.
Add a layer of sliced German sausage on top.
Place sardines, split in half and freed from skin and bones, on top of the pile.
Cut lettuce hearts into quarters and arrange them around the salad.
Garnish with hard-boiled eggs cut into quarters lengthwise.
Make the sauce
For the sauce, mash the flesh of 3 sardines in a mortar until smooth.
Mix in the yolks of 2 hard-boiled eggs.
Add a pinch of cayenne, a grate of nutmeg, and 2 tablespoons each of oil, vinegar, and light wine slowly, beating well after each addition.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the savory fish flavor and the oily richness that carries the dressing.
- Hard-boiled egg yolks
- Thicken the sauce into a smooth, creamy emulsion body.
- Oil
- Adds fat and richness, helping the sauce emulsify and turn smooth.
- Vinegar
- Adds acidity that brightens the sauce and balances the rich fish.
- Light wine
- Adds acidity and aroma that lift the flavor of the sauce.
The step that matters
Adding the oil, vinegar and wine slowly. Adding liquids gradually while beating lets the oil disperse into tiny droplets held by the egg yolk, giving a smooth emulsion. Dumping them in at once can split the sauce into a greasy, watery mixture.
Swap the nutmeg
How well each one fits the dish's main ingredients (fish, capers, lettuce, egg, sauce, vinegar, wine):
- Tarragonfits better
- Parsleyfits better
- Dillfits better
- Nutmegthe original
Fit is the average pairing score against fish, capers, lettuce, egg, sauce, vinegar, wine. Candidates are from the same food group and used in at least 100 recipes.
