These eight great twists on the picnic classic perfectly complement any summertime main dish. If you hate mayonnaise, try the German Potato Salad, which is moistened with white wine vinegar and a little rendered bacon fat. A Moroccan version employs a palate-cleansing pile of minced green parsley. For a salad with Scandinavian flavors, the shocking pink Sildesalat, with smoked herring, dill, and beets can't be, well, beat. Most of these homemade potato salad recipes can be prepared ahead of time and allowed to sit so the starch absorbs the flavors.
