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, becoming tender when boiled and holding their shape when cut.
- Eggs
- Mashed hard-boiled eggs add body, while beaten raw eggs thicken the cooked dressing.
- Sweet cream
- Enriches the cooked dressing, giving it a smooth, rich texture.
- Vinegar
- Adds acidity that balances the richness of the cream, eggs and butter.
- Whipped cream
- Folded in at the end to lighten the salad and add a soft, airy texture.
- Butter
- Adds richness and a smooth mouthfeel to the cooked dressing.
The step that matters
Cook the sauce over low heat, stirring constantly. Beaten eggs can scramble or curdle if overheated. Low heat and constant stirring let the egg proteins thicken the sauce smoothly before it reaches a boil.
