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

What each ingredient does

Potatoes
Provide the starchy bulk that the dressing coats and clings to.
Olive oil
Adds fat and richness, giving the dressing a smooth, silky texture.
Egg yolks
Their fat and lecithin help emulsify the oil and vinegar into a creamy dressing.
Mustard
Helps hold the oil and vinegar together and adds a sharp, tangy flavour.
Vinegar
Adds acidity that brightens the flavour and balances the richness of the oil.

The step that matters

Mixing the dressing into the potatoes. Potatoes are still warm and absorb dressing best while warm, so the flavour penetrates. Once cooled, they absorb less and the dressing can separate or sit on the surface.

Swap the potato
