The heats continue with the new Pairs Challenge, which sees the remaining candidates split into two teams of two, each tasked with cooking the same dish - identical in both appearance and flavour. The contenders are then sent out to Tilbury Docks on the River Thames to prepare lunch for over 100 workers, having to cater in volume for various tastes. Back at headquarters, the four must each cook a faultless two-course meal that will not only be judged by John Torode and Gregg Wallace, but also by former contenders Emma Kennedy, Sophie Thompson and Sam Nixon.
