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

What each ingredient does

Eggs
Beaten eggs cook into the dressing, thickening it and giving it body as it heats.
Sour cream
Adds tang and creaminess, keeping the dressing moist and smooth.
Potatoes
Form the bulk of the salad, holding their shape once cooked and chilled.
Whipped cream
Stirred in at the end to lighten the texture and add richness.
Vinegar
Adds acidity that balances the richness of the eggs, cream and butter.

The step that matters

Heating the dressing until it boils. Beaten eggs can curdle or scramble if overheated, so stirring constantly keeps the dressing smooth while the egg proteins thicken it evenly.

Swap the onion

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

  1. Mustardfits better
  2. Capsicumfits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against potato, celery, egg, pepper, sugar, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
