Hosted by Liam Charles and Tom Allen, it's the semi-final and just four teams remain. For their first challenge, the teams must complete a secret recipe - with an added twist. They must also create an impressive three-tiered cake as well as performing a spectacular piece of gourmet theatre known as live plating - with just three minutes to transform their table, and their cake, into a gastronomic work of art, under the tough gaze of judges Cherish Finden and Benoit Blin.
