Edinburgh

The MasterChef judge visits Scotland's capital, where he heads up the Royal Mile to one of the most documented castles in the world, goes underground to see the centuries-old streets that still remain and learns about the tradition of bagpipe playing. He also learns about Scotland's rich larder with one of its finest chefs Tom Kitchin, helping cook up a feast of grouse and langoustines. Gregg finishes his brief jaunt by joining some locals for an early-morning dip in the North Sea.
