4. Drain and Cool: Drain the potatoes in a colander and let them cool for about 5 minutes.
5. Mix the Dressing: In a large bowl, combine mayonnaise, Dijon mustard, apple cider vinegar, salt, and black pepper. Stir until smooth.
6. Combine Ingredients: Add the cooled potatoes to the dressing mixture, gently folding them until well coated.
7. Add Veggies and Eggs: Stir in the diced celery, chopped red onion, sweet pickle relish, and chopped hard-boiled eggs. Mix until evenly distributed.
8. Taste and Adjust Seasoning: Take a taste and adjust seasoning with additional salt and pepper if necessary.
9. Chill (Optional): For enhanced flavor, cover the salad and refrigerate for at least 30 minutes before serving.
