Chefs Paul Rankin and Nick Nairn visit the Bay of Plenty on the east coast of the North Island, cooking for descendants of George Vesey Stewart. Originally from Co Tyrone, Stewart was responsible for enticing dozens of Ulster families to emigrate to New Zealand in the 1870s, building a community around the small town of Katikati. On the menu are avocado, manuka honey and shorthorn beef, and the chefs get an unwelcome visit in the kitchen from the local fire brigade
