1. Cut potatoes into halves or quarters and place in cold salted water. Boil until fork tender, about 13-15 minutes. Drain and optionally peel loose skins.
2. Mash potatoes or pass them through a ricer for a fluffy texture.
3. In a large bowl, gently fold the warm potatoes with mayonnaise, mustard, green onions, salt, black pepper, and optional paprika.
4. Add the chopped pickles, hard-boiled eggs, and bacon if using. Mix gently to combine.
5. Taste and adjust seasonings, adding more salt, mustard, mayonnaise, pickle juice, or apple cider vinegar if needed.
6. Cover and refrigerate until ready to serve, ideally letting it sit a few hours or overnight for flavors to meld.
