Celebrities compete in a contest of culinary skill. Jim Moir, Angellica Bell, Stephen Hendry, Julia Somerville and Henri Leconte get their campaigns under way.

The first batch of five celebrities undertake three tough challenges in a bid to prove their talent to judges John Torode and Gregg Wallace. Hoping to show they have got what it takes are comedian and actor Jim Moir, TV presenter Angellica Bell, seven-time snooker world champion Stephen Hendry, presenter Julia Somerville and tennis legend Henri Leconte.

The first challenge is the Mystery Box. The contestants must use the ingredients in the box, which include lamb loin, goat's cheese, butternut squash and rhubarb, as well as a basic larder, to create one dish.

The celebrities are then split into two groups to take on the challenge of cooking for the first time in a restaurant kitchen, preparing dishes for paying customers. Jim, Stephen and Henri head to Aster, which is heavily influenced by Nordic and French cuisine, while Angellica and Julia are sent to Temper.

In the final test, the contestants are asked to prepare a two-course menu of their own design in just one hour. The celebrities work furiously in a last attempt to prove themselves to the judges, because at the end of this test one of them will be going home.
