Why it works: Capers and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 372 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
Sardine Salad
Ingredients
Directions
Prepare the dressing
In a bowl, mash the yolks of 3 hard-boiled eggs with 3 boneless sardines.
Add 2 tablespoons of oil, 2 tablespoons of French vinegar, nutmeg, white pepper, and coralline pepper; mix well.
Assemble the salad
Place ½ pound of flaked cooked white fish in a salad bowl; season with salt, pepper, oil, and vinegar.
Layer 4 halved sardines over the fish, then sprinkle with chopped gherkins or capers.
Coat the dressing with another sieved egg yolk and place a ring of cut-up lettuce around the edge.
Season the lettuce like the fish and add diced onion on top before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mashed into the dressing, they add richness and a creamy body.
- Sardines
- Provide the savoury, oily flavour that defines the salad.
- White fish
- Forms the flaked base of the salad, giving it bulk and a mild flavour.
- Oil
- Adds fat and moisture, carrying flavour through the dressing and fish.
- French vinegar
- Adds acidity that brightens the rich fish and egg flavours.
The step that matters
Mashing the yolks into the dressing. Yolks must be mashed smooth with the sardines before the oil and vinegar are added. Adding the oil and vinegar too early can leave the yolk grainy, so the dressing does not emulsify and stays separated.

Fit is the average pairing score against egg, vinegar, nutmeg, pepper, fish, capers, lettuce. 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).
