01 - Place potatoes in a large pot and cover with cold salted water. Bring to a boil over high heat, then reduce to a simmer and cook for 10 to 12 minutes or until just fork-tender. Drain well and allow to cool slightly.
02 - In a large mixing bowl, combine mayonnaise, sour cream, Dijon mustard, apple cider vinegar, garlic powder, smoked paprika, salt, and pepper. Whisk until smooth and well blended.
03 - Add the warm potatoes to the dressing. Gently fold to coat all pieces evenly without breaking them apart.
04 - Add celery, red onion, dill pickles, scallions, and half of the crumbled bacon. Mix gently to distribute ingredients throughout.
05 - Fold in hard-boiled eggs, if using, and half of the chopped herbs. Taste and adjust seasoning as desired.
06 - Cover the bowl and refrigerate for at least 1 hour to allow flavors to meld and salad to chill.
07 - Before serving, garnish with remaining bacon and herbs. Serve chilled or at room temperature as preferred.
