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 cook until tender.
Egg yolks
Emulsify with the vinegar and mustard to give the dressing a creamy, rich body.
Vinegar
Adds acidity that brightens the dressing and balances the richness of the yolks.
Egg whites
Add chopped texture and mild bulk to the salad without making the dressing heavy.

The step that matters

Combining the dressing with the chopped mixture. Mixing gently keeps the potato pieces from breaking down into mash. Cooled potatoes also absorb dressing better than warm ones, so the salad stays well seasoned and holds its shape.

Swap the potato

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