Chef James Martin takes to the skies to explore how the beautiful and unique landscape of the British Isles produces distinct and delicious regional ingredients. He explores Northern Ireland to get an understanding of why the beef from the miniature native cattle, the Dexter, has such a rich and unique flavour. He also visits the east coast and discovers why its lobsters are so prized by chefs. On his journey he creates a Goan lobster curry, and a fillet of Dexter beef served with a garlic and parsley risotto and caramelised onions.
