Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and vinegar into a thick, creamy dressing.
- French mustard
- Helps stabilise the dressing emulsion and adds sharp flavour.
- Oil
- Provides richness and body to the dressing and coats the potatoes.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
- New potatoes
- Form the bulk of the salad, holding their shape when sliced and cooked.
The step that matters
Cook the potatoes until tender. Potatoes that are undercooked stay firm and resist absorbing the dressing, while overcooked ones break apart when sliced or mixed. Tender, intact potatoes take up the dressing evenly.
