Prepare
Cut cold potatoes into round or oblong slices, about ¼ inch thick.
Rub a salad bowl with a small cut onion and a clove of garlic or shallot.
Layer the potato slices in rows in the bowl.

Pour over a dressing made of ⅔ cup oil, ⅓ cup vinegar, pepper, coarse sea salt, chopped parsley, and a pinch of cayenne.

What each ingredient does
- Cold potatoes
- Form the bulk of the salad and hold the dressing between their slices.
- Oil
- Carries fat-soluble flavour and gives the dressing a smooth, rich mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
