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, giving it body and a soft, starchy texture.
Hard boiled eggs
Add richness and a firm, creamy texture to the salad.
Vinegar
Provides acidity that sharpens the flavor and balances the cream and butter.
Mustard
Adds sharp, pungent flavor and helps emulsify the dressing.
Sweet cream
Adds richness and moisture, softening the dressing into a creamy coating.
Butter
Adds fat and richness to the warm dressing base.

The step that matters

Stir in the sweet cream only after the dressing has cooled. Adding cream to a hot, acidic mixture can cause it to curdle or separate. Letting the dressing cool first keeps the cream smooth and evenly blended.

Swap the onion

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

  1. Horseradishfits better
  2. Capsicumfits better
  3. Lettucefits better
  4. Onionthe original

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