The Great British Bake Off

The bunting has been hung and the tent is up, which can only mean one thing - Alison Hammond and Noel Fielding are back to guide a fresh batch of amateur bakers through 10 weeks of challenges set by new judge Nigella Lawson and Bake Off veteran Paul Hollywood. As ever, it all begins with cake week, for which Nigella sets the contestants a stout cake signature, before they get artistic in the technical and serve up a self-portrait showstopper.

It's Biscuit Week and there's a trip Stateside for the bakers in the Signature as they make American-style cookies. In the Technical, it's a journey of a different kind as they travel back in time for a nostalgic classic. But nothing is quite as it seems and they must rely on their taste alone to recreate this beloved bake. And in the Showstopper, a visually striking biscuit mosaic tests the bakers' artistic flair and also gives them the chance to create something that's close to their hearts.

In a first for the show, the bakers face a series of challenges chosen by the viewers, including a signature that sees an invasion of familiar faces into the tent. They also face a mystery box in the technical round, before a showstopper in which they unleash their inner fashionistas by serving up wearable bakes.

The bakers are hoping for a Hollywood handshake this week as they tackle bread, the steely-eyed judge's speciality. The challenges include a garlic bread signature and a showstopping bread display - not to mention one of the most disastrous technicals in the show's history. Who will be dusting themselves off and hanging up their apron?

Noel Fielding and Alison Hammond present as the bakers serve up their best desserts, and for their first challenge they face a staggered start signature in which they make self-saucing puddings. They also face a British classic in the technical and have to produce a selection of classic retro puddings in the showstopper. Paul Hollywood and Nigella Lawson taste their efforts and decide who is hanging up their apron.

Noel Fielding and Alison Hammond lead the bakers through pastry week, where they make hand-held savoury pies in the signature challenge before attempting a Polish choux dessert in the technical. Finally, their skills are pushed to the limit when they are challenged to make an eye-catching decorative pie for the showstopper. Nigella Lawson and Paul Hollywood taste their efforts.
