My husband and I retired from central Illinois to Florida. Several times, a friend gave us grapefruit from his backyard tree. One day I was going to make a lemon pineapple gelatin salad and discovered I didn't have pineapple. So, I cut up a fresh grapefruit and used it in the salad. It was good, and I tried adding other fruits until I came up with this recipe. Doris Wendling, Palm Harbor, Florida.
