This is my family recipe. It must rest for one day.
2x potato I cook them quartered in their jackets, cool, peel and chop. Not the easiest way, but preferred.
2x hardboiled eggs, cooled, peeled, sliced
x scallions, chopped
x bacon, cooked to semi-crisp, chopped
mayonnaise, mustard (I use dijon), celery salt, ground black pepper
optional: dash cayenne
Another option from Nana: splash of Italian dressing, any type.
