Ade in Britain: Northumberland

Adrian Edmondson's journey continues with a visit to Northumberland, where he rides the town boundary at Berwick-upon-Tweed on horseback, smokes kippers at Craster and meets a couple passionate about potatoes. He also cooks pan haggerty with kippers for folk-singing sisters Becky and Rachel Unthank in the grounds of Langley Castle in Hexham
