McCormick Island, Saint John, New Brunswick

Top chefs Paul Rankin and Nick Nairn continue on their culinary road trip in Canada. This week they're in the province of New Brunswick, cooking for an Ulster Scot descendant whose ancestors settled on an island in the Saint John River. With no electricity and only barbecues to cook on, the chefs prepare a 3 course meal on the island using freshly caught herrings, foraged mushrooms and recreate a campsite favourite for dessert – s'mores!
