The Florida Keys are a hot vacation spot. But you don’t have to trek to the southern most point to enjoy their famous key lime. This citrus-glazed dessert has enough tropical flavor to get your fill of Florida’s finest. It’s light, tangy and hardly anything like the traditional pound cake. Every round inch is a sweet indulgence that whisks you away. Remember, it’s five-o-clock somewhere.
