Start by washing the potatoes thoroughly. Peel the potatoes and cut them into bite-sized cubes and place them in a large pot. Cover with water and add 2 teaspoons of salt. Bring to a boil over medium-high heat, then reduce the heat and simmer for about 10-15 minutes, or until the potatoes are fork-tender. Drain and let cool slightly.
While the potatoes are cooking, prepare the hard-boiled eggs. Place the eggs in a saucepan and cover them with cold water. Bring to a boil, then cover and remove from heat. Let the eggs sit in the hot water for 10-12 minutes. Once done, drain the hot water and place the eggs into a bowl of ice water. Peel and chop the eggs.
In a large mixing bowl, whisk together the mayonnaise, apple cider vinegar and yellow mustard. Add in the sweet pickle relish, chopped celery, and diced onion.
Gently fold in the cooled potatoes and chopped hard-boiled eggs and coat evenly in the mayonnaise mixture. Season with salt, pepper and paprika. Garnish with fresh herbs, if desired!
