Bake Off: The Professionals

In the first of two heats, judges Cherish Finden and Benoit Blin set a pair of exceedingly tricky challenges for six new teams. The first requires them to finely craft two batches of perfectly uniform miniature classics - 24 Linzer tortes and 24 Bakewell tarts - in just three and a half hours. For the second challenge - the Showpiece - the teams are required in five hours to reinvent a classic dessert - the red velvet cake. Can the teams transform the ordinary into the extraordinary? At the end of the two days, one of the teams must leave the competition.

The five remaining teams of professional pastry chefs face the scrutiny of judges Cherish Finden and Benoit Blin in Britain's toughest patisserie competition. No pastry is left unturned in a challenge requiring the teams to create 24 layered fruit cake slices and 24 lemon-shaped desserts. For their final challenge, the teams have five hours to create an eclair tower to serve 48 people. So whose patisserie journey will continue and whose will come to an end?

Hosted by Liam Charles and Tom Allen, the four teams face Asia week with the judges Cherish Finden and Benoit Blin pushing them to their limits with a secret recipe challenge. For the Showpiece the teams construct chocolate towers with a moving part. By the end of the show, one team will have to leave the competition.

This time, judges Cherish Finden and Benoit Blin set the teams two tricky challenges. The first one requires two batches of perfectly uniform miniature classics - 24 gateaux Basques and 24 tartes Tatin, in just three and a half hours. For the showpiece challenge, the teams have five hours to reinvent a classic dessert. The dessert is the Battenberg, with teams striving to create an extraordinary version of this teatime favourite.

The remaining teams feel the heat rising as they must produce pristine, perfect cheesecake slices, pear-shaped desserts, and a themed pièce montée with two different flavours of choux buns.

Chocolate Week features a secret recipe challenge, and a Showpiece in which the teams have five hours to produce a magnificent sun, sea and sky-themed extravaganza with three types of chocolates. Their creations must demonstrate a mastery of chocolate, consummate technical ability, artistic flair - and a moving part.

The best six teams from both sets of heats are combined, facing new rivals and new challenges as they battle it out for a place in the quarter-final. For Holiday Week, the teams must create 24 classic brioches polonaises and 24 savoury Danish pastries in just four hours. For their next challenge, the teams take judges Cherish Finden and Benoit Blin on a journey with their holiday-themed Showpieces.

In the quarter-final of the competition, the teams are challenged to prepare 24 ice-creams and 24 doughnuts in just four hours, before creating a spectacular Showpiece incorporating confectionery, sugar work and chocolate. The lowest-ranking team must leave the competition, whilst the remaining four secure their place in the semi-final.

Just four teams remain for the semi-finals, with challenges including the creation of an impressive tower of tarts and a spectacular piece of gourmet theatre known as live plating. At the end of the challenge, the teams are given three minutes to transform their table - and their cake - into a gastronomic work of art, with three of them securing their places in the grand final.

The three remaining teams must fight tooth and mixing bowl to be crowned the winners of this incredibly tough patisserie competition. Judges Benoit Blin and Cherish Finden have for the first time set two challenges for the final - four hours to create a stunning afternoon tea and seven hours to create mind-blowing wedding feast. So which team will impress the judges with their precision, passion and patisserie prowess, to be crowned the winner of Bake Off: The Professionals?
