The hunt for a champion continues as the final five celebrities are welcomed to the challenge in the last of the heats. Trying to impress judges John Torode and Gregg Wallace are actor Lisa Maxwell, professional dancer AJ Pritchard, furniture restorer Jay Blades, international recording artist Stella Parton, and DJ and broadcaster Clara Amfo. The first challenge for the five hopefuls is the Mystery Box, the infamous test of imagination and creativity. The contestants must use the ingredients in the box to create one dish in 50 minutes. The celebrities are then split into two groups to take on the challenge of cooking for the first time in a restaurant kitchen, preparing dishes for paying customers. For the final test of culinary creativity it's back to the MasterChef kitchen, as the contestants are asked to prepare a two-course menu of their own design in just one hour. At the end of this test one of them is sent home.
