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 ↓
Potato Salad
Ingredients
Directions
Prepare
Finely chop the onion as if it were grated.
Cut the cold boiled potatoes into small cubes.
Optionally, mix the chopped green pepper with the onion.
Dress the potatoes
Mix the potatoes and onion with the oil, ensuring each piece glistens.
Add vinegar one tablespoon at a time, mixing thoroughly after each addition.
Transfer the mixture to a salad bowl, shaping it into a firm mound.
Cover the mound with mayonnaise dressing.
Decorate and serve
Divide the mound into six sections using capers, olives, or chopped lettuce.
Fill each section with cooked yolks, chopped whites, and chopped beets.
Top with a tuft of lettuce hearts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad, giving it body and a soft, starchy texture.
- Oil
- Coats the potato pieces, adding fat and a smooth, glossy mouthfeel.
- Vinegar
- Adds acidity that brightens the flavour and balances the oil and mayonnaise.
- Mayonnaise dressing
- Adds richness and moisture to the surface and binds the salad together.
- Eggs
- Cooked yolks and whites provide richness and a mild, creamy filling for each section.
The step that matters
Adding the vinegar. Add it one tablespoon at a time and mix after each addition. Vinegar absorbed unevenly leaves some potato pieces sharp and others bland, and the soft potatoes can break apart if overmixed.
