As a young bride, my mother-in-law volunteered to bring potato salad to a luncheon. She had never made it before, but she was sure she could figure it out. She knew potatoes and hard boiled eggs. She remembered something crunchy -- celery -- and she remembered something green. She put in chopped green pimiento olives, not pickle relish! Her mistake turned out to be an inadvertent stroke of genius. You won't believe how good it is!
