A picnic staple, the classic mayonnaise-based chicken salad is creamy and delicious. We like to keep our chicken salad simple, making it with hard-boiled eggs, celery, pickle relish, and onion and serving it with saltines. Chicken salad is a retro dish—we have a couple of versions that date back to the 1950s. One version, served at Neiman Marcus department stores, is made extra rich with whipped cream and is studded with grapes and sliced almonds. Another, made for Queen Elizabeth II's coronation lunch, is flavored with curry powder and mango chutney.
