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.
Sandi Toksvig and Noel Fielding welcome 12 contestants to the tent, where judges Paul Hollywood and Prue Leith oversee them in three challenges. This year, the competition kicks off with Biscuit Week, and the bakers are challenged to make signature biscuits that will say something both about them and a place in the British Isles, before tackling one of Paul's childhood favourites in the Technical. Finally, the bakers are tasked to make a 3D biscuit portrait in their first Showstopper.
It's week two and the remaining 11 bakers face Cake Week - kicking off with a crowd-pleasing signature challenge. Next, the bakers face Prue Leith's first technical, a complicated cake with a very unusual ingredient. Finally, an ambitious chocolate-collared showstopper turns up the heat in the tent. Who will rise to the various tasks - and who will melt under the pressure? Sandi Toksvig and Noel Fielding present, while series regular Paul Hollywood and Prue pass judgement before another baker leaves the contest.
It's Bread Week, and the ten remaining bakers have a lot to prove with three tough challenges set by judges Paul Hollywood and Prue Leith. There is a teatime fruity favourite Signature; a deceptively simple time-test of a Technical with an international flavour; and an ambitious Showstopper that's the largest bread sculpture challenge ever set in the tent. Only one can claim Star Baker, while one of them will leave the tent for good.
It is Dessert Week and judges have set three sticky challengers to test the remaining nine bakers. They must create a cracking meringue Signature, a wobbly Technical and a complex chocolate showstopper that promises to reveal all.
It's Spice Week, and Paul Hollywood and Prue Leith task contestants with a teatime favourite Signature. The Technical means the bakers are tested with a tricky Arabian pastry. And, finally, they take on a fiddly Showstopper that promises to be anything but light work.
It is Pastry Week, and Paul and Prue are looking perfection - with savoury and sweet samosas, a classic French technical, and for the final challenge, a daunting majestic pie fit for a banquet.
It is a Bake Off first with Vegan Week. Prue and Paul have set three very different challenges to test the remaining bakers including savoury pastry signature without butter, a cracking technical and a risky but spectacular showstopper.
Volkommen to Danish Week with a bread signature requiring style and substance, a spherical technical and an elaborate pastry showstopper fit for a Danish birthday party and everyone is out to impress.
It is semi-final week for the remaining contestants, who know they are just three patisserie challenges away from the biggest day in their baking lives. First comes the Signature and a deceptively simple challenge, with Paul Hollywood and Prue Leith looking for perfection, followed by Prue's complex, multi-layered Technical. The pressure intensifies when they are asked to create a spectacular Showstopper that could grace a Parisian patisserie - but who has the skill to reach the Bake Off final and who will fall at the final hurdle?
Noel Fielding and Sandi Toksvig present the 2018 grand final, as the three remaining bakers compete to impress judges Paul Hollywood and Prue Leith and take home the trophy. For the final three challenges, they must prepare and decorate doughnuts, followed by a deceptively simple technical, and climaxing with an intricate, multi-layered, edible landscape showstopper.
