The four remaining celebrities face three more culinary challenges, as they battle for a place in the semi-finals. The contestants are split into two teams and sent out on their first mass catering assignment at the Royal Veterinary College in Hertfordshire. There, they must make lunch for more than 100 members of staff and students, using an array of ingredients including diced lamb, hake fillets and salmon, as well as a range of fruit and vegetables. Back in the kitchen, the celebs prepare a two-course meal that will be judged by former contestants Alexis Conran, the Rev Richard Coles and Andi Peters.
