1Peel and dice the 4 large potatoes into bite-sized pieces.
Place the diced potatoes in a large pot and cover with water. Add a pinch of salt.
Bring the water to a boil and cook the potatoes until they are tender, about 10-15 minutes.
Drain the potatoes and let them cool completely.
In a large mixing bowl, combine the cooled potatoes, 1/2 cup chopped pickles, 1 cup mayonnaise, 2 tablespoons mustard, and 1/2 cup sour cream.
Add 1 teaspoon salt and 1/2 teaspoon celery salt to the mixture.
Gently mix all the ingredients together until well combined.
Chill the salad in the refrigerator for at least 1 hour before serving.
Serve the Pickle and Potato Salad cold and enjoy!
