Thank you @farm-mom, I learned to make it plain, nothing but potatoes, boiled egg, sweet relish and mayonnaise.
That is cool, but I am a bit more complex; I like some CRUNCH (raw celery and raw onion) and I like some spice/snap (vinegar in the dill relish) and sometimes I even add some pepperoncini's for an added touch of spike.
I'm an "use what you have on hand" kind of cook.
