One of the strangest potato salad recipes I've ever seen. You boil the potatoes in the skins, peal, and toss with 1/4 C apple cider vinegar. Separately, while the potatoes are soaking up the apple cider vinegar, you cut up celery, onion, etc. and toss them with mayo-based dressing. Mr. Big Food used the Thousand Island we've been having on our salads. And then you combine it all. Delicious.
