Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Form the body of the salad, with a soft, smooth texture once sieved.
Oil
Adds fat and richness, coating the potato and giving a silkier mouthfeel.
Vinegar
Adds acidity that brightens the flavour and balances the richness of the oil and yolks.
Hard boiled egg yolks
Add richness and body, helping bind the dressing to the potato.
Mustard
Adds sharp, pungent flavour and helps emulsify the dressing.

The step that matters

Mix in the oil, vinegar, and yolks. Adding the oil gradually while mixing helps it emulsify with the yolks and vinegar; if added too fast or unevenly, the dressing can separate and look greasy rather than creamy.
