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):
- Horseradishfits better
- Lettucefits better
