Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Hard boiled and beaten eggs add body, richness, and a creamy texture to the salad.
Vinegar
Provides the sharp acidity that balances the sugar and richness of the dressing.
Sugar
Sweetens the dressing, offsetting the sharpness of the vinegar and mustard.
Butter
Adds fat and richness to the dressing, softening its sharp edges.
Cream
Adds richness and smoothness, helping the dressing coat the potatoes.

The step that matters

Cooking the dressing over low heat. Beaten eggs in the dressing can curdle or scramble if heated too fast. Gentle heat with constant stirring thickens the mixture smoothly.

Swap the onion

How well each one fits the dish's main ingredients (potato, egg, celery, pepper, mustard, vinegar, butter):
