French dressing or cooked dressing: Adds moisture and tang that coat the potatoes and keep them from drying out.
Hard-boiled egg yolk: Adds richness and a creamy, crumbly texture to the salad.
Onion: Contributes sharp aromatic flavour that cuts through the richness.
Celery: Adds crisp texture and a mild, fresh bite.
