Bake Off: The Professionals

Ellie Taylor and Liam Charles introduce guest judge Will Torrent, the senior development chef at Waitrose, who sets the six remaining pairs a retail product challenge in which they must bring the humble apple to the fore, celebrate autumn and spotlights trending ingredients. For their second challenge, they build a 'World of Candy' complete with a pâtisserie pick 'n' mix. Then all that remains is for Benoit Blin and Cherish Finden to decide who has hit the sweet spot and who will be left with the sour taste of failure.

Ellie Taylor and Liam Charles present the quarter-final in which the teams create two batches of 24 afternoon tea desserts, inspired both in look and flavour by their favourite teatime treats. Things then take a darker turn as they make creepy, gravity-defying piñatas for a Circus of Horrors-themed spectacular, filled with edible delights that fall to the table when smashed open by Cherish Finden and Benoit Blin.

Ellie Taylor and Liam Charles present as the four remaining pairs take on the longest semi-final challenge in the show's history - seven gruelling hours to create edible floating showpieces celebrating summer holiday vibes, complete with perfectly matched choux buns. But before that, one chef from each team takes on an individual test to serve up the classic meringue dessert île flottante (floating island) with no recipe to help them. After all their efforts, Cherish Finden and Benoit Blin decide who is worthy of a place in the final.

In one last epic task, the finalists take on a monumental 12-hour Masquerade Ball Banquet challenge with a brutal twist halfway through! Who'll be feasting on glory?
