This is what I like. Mother and my Aunts made their Potato Salad with half cooked potatos. I boil my potatos until done. just as if I was making mashed potatos.for about 3 pounds of potatos I add one or two finely chopped onions. one finely chopped stalk of celery. a good cup of sweet salad cube pickles. salt and pepper and Dukes mayo . then mash it all up with a potato masher until smooth. taste and if it needs it a tablespoon or two of vinegar wont hurt. this is how my Granny Craig made it and its still my favorite.
