Paula McIntyre visits Nashville, the world’s country music capital. She joins the queue at Arnold’s Country Kitchen, a Nashville institution, to sample meatloaf, turnip greens and their famous fried green tomatoes. Paula then heads to a music venue to hear a special performance by Kirwan, a duo from Northern Ireland who left home for a new life in Music City. And she joins the congregation’s best cooks at the Second Presbyterian Church at a celebratory Scots-Irish pot luck lunch. At her outdoor mountain kitchen, Paul cooks a sugar plum and hazelnut cobbler and barbecued pork shoulder with corn on the cob, kale and squash.
