Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk and body of the salad.
- Eggs
- Thicken the hot vinegar mixture into a creamy, smooth dressing.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness.
- Mustard
- Adds a sharp, pungent flavour to the dressing.
- Celery seed
- Adds an aromatic, savoury celery flavour.
The step that matters
Add the beaten eggs while the vinegar is hot, then stir until smooth. Egg proteins thicken when heated, so the hot vinegar cooks the eggs into a smooth dressing. Adding them to vinegar that is too hot or leaving them over heat too long can make them curdle or turn grainy.
