Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Form the body of the salad, holding their shape when sliced while hot.
Bacon or ham fat
Adds richness and fat that coats the potato slices and carries flavour.
Vinegar
Adds acidity that gives the salad its sharp, tangy flavour.
Onion
Adds sharp aroma and pungent bite to the salad.
Hard-cooked eggs
Add soft texture and mild richness to the salad.

The step that matters

Dressing the potatoes while hot. Warm potato slices absorb the hot fat and vinegar far better than cold ones, so the flavour soaks in evenly. Mixing gently keeps the slices intact rather than breaking them into mush.

Swap the onion
