It's the second semi-final, and the remaining six celebrity cooks continue to battle for the MasterChef title. For their first task, each of the six benches in the MasterChef kitchen contains the ingredients and recipe to make a different classic dish from around the world, including chicken kiev, a Portuguese fish stew, lamb koftas and queen of puddings. To stay in the competition, the celebrities must pick a bench at random and then cook the dish that's on it. Next, the remaining five celebrities face their most daunting challenge yet - to prepare a five-course dinner for the Chelsea Pensioners in celebration of HM the Queen's 90th birthday. However, they won't be cooking their own dishes. They will be cooking the menu of Nigel Haworth of Michelin-starred Northcote Manor. Finally it's back to the MasterChef kitchen, where the final five must each create one exceptional dish that celebrates the life of someone important to them.
