German Potato Salad with Würstchen

Boil potatoes, skin on, ideally the day before preparing the salad. Then peel, leaving the potatoes whole, and keep cool and covered until ready to put together the salad.
Boil your eggs (use instructions above for medium-boiled eggs, making sure to boil a few additional eggs for garnish). Let them cool and dice.
Medium dice the pickles and Wiener sausages.
Combine everything in a medium-sized bowl.
Slice the potatoes into about 1/4 inch thick slices and combine them in a bowl with the small diced onion.
To make the dressing, in a medium-sized pot, combine broth, pickle juice, mustard and bring to a boil. Add salt, pepper and sugar to taste (it should not be too sour or else grandma gets mad!).
Let cool slightly, then pour over potato-onion mixture and let marinate for 10 minutes before folding in the mayo.
Combine with the diced pickles, eggs, and crisped bacon pieces. Keep cool in the fridge, and garnish before serving with more eggs, pickles, and parsley before serving.
Warm the Wiener sausages in a large pot of cold water, then warm them, but do not let them boil.
Serve family-style and enjoy! Guten Appetit!
