Tensions in the kitchen build as Nigella's team is down to two and 12 remain in the competition. With what would seemingly be a simple challenge -- to create the perfect sandwich -- things become heated among judges/mentors Anthony Bourdain, Nigella Lawson, Ludovic Lefebvre and Brian Malarkey and their teams. Chefs Rich Torrisi and Mario Carbon act as guest judges. One contestant will win immunity and two will be eliminated.
