The competition intensifies as the eight rivals compete to cook the final course, dessert, at the banquet. The guest judge is Dame Jessica Ennis-Hill, a heptathlete who became one of the most celebrated British competitors when she won gold at London 2012. She's joining Michelin-starred chef Tom Kerridge, restaurateur Nisha Katona and food podcaster and comedian Ed Gamble on the judging panel to select the menu's grand finale.Desserts are famously tricky to pull off in the heat of the Great British Menu kitchen, so they have their work cut out. This is the last chance the chefs have of cooking a course at the banquet, so tensions are running high as the rivals battle it out for the final time.Once a winner has been decided, one chef will be surprised by being asked to cook the banquet's canape. Will this be additional work for an existing winner or a chance at cooking at the banquet for a chef who hasn't won a course?
