Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the salad, absorbing the warm dressing as they stay hot and tender.
- Butter
- Browns in the skillet, adding a nutty, toasted flavour to the dressing.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the butter.
- Hard-boiled eggs
- Add richness and a soft, creamy texture to the salad.
The step that matters
Pour the hot mixture over the salad while the potatoes are still warm. Warm potatoes absorb the vinegar dressing far better than cold ones, so the flavour soaks through the slices. If they cool first, the dressing mostly coats the surface and the salad tastes flat.
