Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and absorb the warm vinegar dressing.
- Bacon
- Adds savory, smoky flavor and fat that carries into the vinegar dressing.
- Vinegar
- Provides the sharp acidity that defines the dressing and balances the fat.
- Boiled eggs
- Add richness and a soft texture to the salad.
- Onion
- Contributes sharp, pungent flavor that mellows in the warm dressing.
The step that matters
Pour the heated vinegar mixture over the salad just before serving. Potato slices absorb warm dressing best while hot, and vinegar added too early can soften the salad and dull its texture. Serving soon after dressing keeps the potatoes tender but not mushy.
