The Great British Bake Off sees passionate home bakers take part in an elimination competition to test every aspect of their baking skills. Each week the surviving bakers are put through three challenges in a particular baking discipline, such as cake, pastry, pies, bread, or biscuits.
Round One is the Signature Challenge, which contestants will have had a chance to practice. However Round Two, the Technical Challenge, is unknown to them until filming, and they are given identical ingredients and a vague recipe to follow. Finally, the Showstopper Round tests their ability to impress the judges with outstanding workmanship, decoration, and design.
Judging the baking are professional baker Paul Hollywood and food writer Mary Berry, who was replaced by restaurateur Prue Leith after the show's move from the BBC to Channel 4.
This series kicks off with cake week, with challenges including a retro classic technical that demands precision and intricate decoration, and a showstopper birthday cake, taking the baker's dozen back to their childhoods.
It's crunch time with biscuit week, starting off with a luxurious chocolate coated signature bake, then a snack with family significance for Paul and an eye-catching showstopper.
It's Bread Week and the bakers tackle a signature bake designed to be shared. Then, the bakers must tackle a deceptively simple summer staple in the Technical and to finish there is an ambitious Showstopper.
It's Dairy Week and Prue and Paul have set some tricky challenges including a Technical that dates back to Henry VIII and a Showstopper usually found at Indian weddings.
This time the judges set challenges inspired by the roaring twenties, including a slapstick Signature and a tiered Showstopper that's a take on their favourite tipple.
The cake layers stack up in an elegant and challenging bake for Dessert Week. There's also a spherical celebration cake and a Technical where success lies in precise decoration.
This week is a special festival-themed round of the culinary competition. The episode kicks off with a signature challenge in which the bakers must draw inspiration from celebrations across the world. For the technical round, the contestants find the makings of a classic deep-fried Italian dish lurking beneath the mysterious gingham cloths.
Noel Fielding and Sandi Toksvig host as the remaining bakers' knowledge of pastry is tested. The Signature challenge is a savoury take on a French classic, there's a multi-layered Moroccan Technical, and a towering Showstopper that requires not only an expertise with pastry, but also a solid grasp of structural engineering. With a place in the semi-final at stake, who will win the coveted Star Baker title from judges Prue Leith and Paul Hollywood?
Noel Fielding and Sandi Toksvig present the semi-final of the baking contest, which tests the four remaining bakers' skills with patisserie. There are only three places in next week's final, and this round of challenges will determine who does not make the cut. The signature dish requires a delicate dome and a perfect finish, while for the technical, the bakers must take croquembouche to the next level. Finally, for the showstopper, they must use all their skills to construct an edible display case.
Noel Fielding and Sandi Toksvig host the final of the culinary competition. As family and friends gather on the lawn outside, the last three bakers enter the tent to prepare a chocolate cake as their signature bake. For the technical challenge, they must master that most delicate of dishes, the souffle, and finally for their showstopper, they must create an edible illusion using only cake, sweet bread and biscuits.
Last in the series.
