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 and hold the dressing as they absorb it.
Eggs
Thicken the dressing as they cook and add richness to the salad.
Vinegar
Adds acidity that sharpens the dressing and balances the sweetness.
Mustard
Adds sharp flavor and aroma to the dressing.
Pickles
Contribute crunch and tangy flavor to the salad.

The step that matters

Cooking the dressing over low heat. The beaten eggs can scramble if heated too fast. Low heat with constant stirring lets the egg proteins thicken the dressing smoothly.

Swap the onion

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

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

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