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 soak up the dressing as they absorb its flavour.
Vinegar
Adds acidity that brightens the dressing and balances the starch and fat.
Butter
Adds richness and body to the warm dressing.
Mustard
Adds sharpness and helps emulsify the dressing.

The step that matters

Pour the hot dressing over the potatoes. Warm potato starch absorbs dressing far better than cold potatoes, so the flavour penetrates. Tossing gently keeps the slices from breaking apart.

Swap the potato

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

  1. Horseradishfits better
  2. Lettucefits better
  3. Capsicumfits better
