The four remaining contenders face more culinary challenges as they battle for a place in the quarter-final. In previous years they have been sent to work with a professional chef - but this year the chef is coming to the studio, starting with Nisha Katona, who challenges the celebrities to cook an Indian dish from her restaurant menu. In addition the hopefuls must identify different types of cheese and make a classic pasta carbonara.

Penny Lancaster, Megan McKenna, Melanie Sykes, Patrick Grant and Nabil Abdulrashid compete in this week's heats.
