In the fourth and final week of heats, the celebrities up for the culinary challenge are TV presenter Kem Cetinay, double gold-medal-winning Paralympian Kadeena Cox, journalist Gavin Esler, Strictly Come Dancing's Johannes Radebe and actor Michelle Collins.
The first challenge for the five hopefuls is the Under the Cloche test. In front of each celebrity is a cloche, underneath which is an ingredient. Each celebrity has a different ingredient and must create one dish that showcases the ingredient and demonstrates to the judges they have potential. Then it's the Street Food Challenge.
The celebrities must taste a popular street food dish and try to identify the ingredients that are in it. Then they must cook the dish without a recipe, using only their instincts about how it is made. This time, the dish is a Turkish classic, gozleme with baba ganoush.
In the final test of their culinary creativity, the contestants are asked to prepare their Dinner Party Dish - something they would cook to impress if someone was coming round to eat. At the end of this test, one of them will be sent home.
