Created at New York's Waldorf-Astoria Hotel in 1896 by the maître d'hôtel, (dining room manager) Oscar Tschirky, the Waldorf salad was an instant success. The original version of this salad contained only apples, celery and mayonnaise. Here is a new way to enjoy this refreshing summer salad--Blueberry Waldorf Salad.
