Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

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.
