McCulloch Family Uber Traditional Potato Salad

O.K. this is one of those family recipes that you can't get them to give you easily. Its not written down; they have to show you, 'cause they just sort of make it.

Red Potatoes (peeling your option)
Hard Boiled Eggs (usually an egg per pound of potatoes)
Celery
Onion
Mayonnaise
Dijon Mustard
Pickle Juice (or Apple Cider Vinegar)

I wash and boil the potatoes, dicing after they cool, leaving the peels on. Boil & dice the eggs. Dice the celery and onion. Combine all the diced ingredients. In a separate bowl add mayo and mustard in a 2:1 (maybe 1 & 1/2) ratio, blend. Add a splash of pickle juice and salt and pepper to taste. My dressing can NOT taste like mayo, and the spicy bite of the horseradish of the dijon must be mellow to not noticable, with a little bit of tart from the vinegar.
