After four weeks of competition it is the first of the semi-finals, and the best eight cooks remain. The celebrities must now cook a feast for 90 of the staff and volunteers at the Black Country Living Museum in Dudley, West Midlands, in specially constructed marquee kitchens. Split into two teams, it's a race against the clock as the celebrities must design and create four mouthwatering dishes each (a meat, fish and vegetarian dish, and dessert) from a selection of ingredients, including pork belly, beef rump, mackerel and whole haddock, as well as a selection of fruit and vegetables, and herbs and spices. Next it's back to the MasterChef kitchen, where they face an invention test with a difference. Each contestant is given their favourite ingredient, ranging from steak to rabbit, as well as lobster and butternut squash. They have just 90 minutes to cook a dish that showcases that ingredient to keep them in the competition. At the end of this challenge more celebrities are sent home.
