text:  This is Travel with Rick Steves. We've been talking with Matthew Gavin Frank. It's been a sweet tour of the South. Matthew's book is The Mad Feast, an ecstatic tour through America's food. And Matthew, we're out of time. I just want to finish with one more state. Of course, there's lots more states, but tell me just for an example about how Mississippi has an iconic dish and what that might teach us about the state of Mississippi.
