Enter a new tradition of summer potato salad making with this tangy classic, German-style. To make the dressing, boil white and cider vinegars with sugar, salt and black pepper, and once cool, combine with sour cream and mayonnaise. When your red potatoes are cooked and cooled, combine with onion, parsley, chives and the dressing, then chill for at least a couple of hours, to allow the flavors to develop. When ready to serve, stir in chopped bacon and roll out for general happiness at the potluck or your family meal! Get the recipe for My Tangy German Potato Salad.
