Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the bulk and creamy body that forms the base of the salad.
- Boiled potatoes
- Add starchy body, so the salad holds together and feels smooth when sieved.
- Olive oil
- Adds fat and richness, carrying flavour and giving the mixture a smooth texture.
- Vinegar
- Adds acidity that brightens the dish and balances the richness of the oil.
- Mustard
- Adds sharp flavour and helps emulsify the oil and vinegar into the mixture.
The step that matters
Stir in the olive oil and vinegar. Adding oil and vinegar gradually while mixing helps them emulsify into the smooth base. Adding them all at once can make the salad separate and look greasy.
Swap the potato
How well each one fits the dish's main ingredients (egg, onion, mustard, olive, vinegar, anchovy, sauce):
- Horseradishfits better
- Shallotfits better
