A potato salad about potatoes - that tastes like potatoes! The magic is to use baking potatoes, fresh cooked, skin on, peeled, and diced while still warm and sprinkled with just enough red wine vinegar to enhance the potato taste. Chopped celery, sweet onion and hard boiled eggs add texture and flavor. The mayonnaise, mixed with the crumbled potato and egg yolk resuts in a creamy, dreamy salad. For the really - really best potato salad, make this an hour or two before serving, cover, let stand at room temp. - then add the mayonnaise and mix.
