From chabad.org with small changes. One of the biggest changes was reducing the amount of lemon juice from three quarters of a cup down to one quarter cup. You can add more lemon juice if desired. Go easy on the allspice, too. Start with a small amount.
Boil the potatoes (and carrots if using) in large pot until tender, about 20 minutes.
Dressing: As the potatoes boil, whisk together the dressing and set aside.
Drain the potatoes and cool briefly. Once cool enough to handle dice the potatoes and place in medium mixing bowl. Add the celery and leaves.
Pour the dressing over the cooled potatoes. Toss gently to combine the ingredients.
Peel the eggs and cut into fourths. Arrange the hard boiled eggs around the edge of the bowl and garnish the top of the potato salad with lemon zest and fresh chives or other suitable fresh herb (Italian parsley or scallions.)
Cover and refrigerate. You can serve the potato salad chilled or at room temperature.
