Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the bulk of the salad and absorb the warm dressing for body.
- Cold boiled ham
- Adds savory meaty flavor and chewy texture to the salad.
- Hard boiled egg yolks
- Mashed with mustard, they thicken the dressing and add richness.
- Vinegar
- Provides sharp acidity that balances the rich yolks and butter.
The step that matters
Letting the yolk mixture boil in the vinegar. Egg yolks thicken when heated, but if the mixture boils too hard or too long it can curdle or turn grainy. Whisking the smooth paste into the warm vinegar keeps the dressing silky.
Swap the potato
How well each one fits the dish's main ingredients (ham, egg, vinegar, butter, mustard):
