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 absorb the dressing as they are sliced thin.
- Olive oil
- Adds fat and smooth richness that coats the potato slices.
- Vinegar
- Adds acidity that brightens the flavour and sharpens the dressing.
- Mustard
- Adds sharp, pungent flavour and helps the oil and vinegar blend together.
The step that matters
Stirring the potatoes. Thin potato slices break easily, so each addition should be folded in lightly and gently. Rough stirring crumbles the slices into mush and makes the salad look broken, while gentle folding lets the dressing coat the slices evenly.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, olive, parsley, onion, celery, mustard, vinegar):
- Capersfits better
