In episode one, Michelin star Chef Tom Kerridge travels the country to find out what makes the best fish and chips and the trade secrets behind them, leading him to one of Britain's oldest fishing ports, Brixham Harbour. There, three of the Nation's top chippies are invited to take part in a contest: each is passionate about their own style of cooking but they all have very different ideas about what makes the best fish and chips. For one it's haddock and beef dripping, for another it's cod, and for the third it's a re-invention of the dish itself.It's down to Tom and his expert judge, fish restaurateur Mitch Tonks, to decide who makes the best takeaway on the day, while Cherry Healey discovers that the origins of our national dish aren't actually British at all.
