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
