The last of the semi-finals sees the remaining celebrities tasked with making the pie of their choice, sweet or savoury, from a wide range of ingredients. Next, they have to prepare a five-course lunch in celebration of over 40 years of the BBC's Antiques Roadshow, cooking a menu created by top chef Paul Askew. Then, it's back to the MasterChef kitchen, where they must each create one exceptional dish inspired by someone they love or admire. For the cook who fails to make the grade, their competition will be over. The remaining four will go through to Finals Week.
