Gordon heads off the tourist track into impenetrable north-east India, home of the country's best-kept culinary secrets. Leaving the 21st century behind, he immerses himself in the life of a local meat-loving tribe in Nagaland, once better known for head-hunting than their curries. Then he's off to Assam to enter a housewives' competition to find the best Assamese dish; and finally he sets up shop among the street food stalls of Calcutta to try and tempt the local foodies into buying north-east curry - Ramsay style.
