Bake Off: The Professionals

Liam Charles and Ellie Taylor welcome back the best three teams from each set of heats for a chocolate-fuelled pursuit to reach the final. For their first challenge, the chefs create two batches of chocolate bars, after which they must create a hanging showpiece made entirely from chocolate and delicately suspended from the ceiling, inspired by a Mythical Beasts theme.

It's the quarter-final, and the five remaining teams take on a secret challenge to create a plated dessert celebrating caramel for each of the judges. For their second challenge, the teams have five hours to create a display of frozen lollipops presented within a delicate sugar sculpture, inspired by a Winter Wonderland theme.

Guest judge Nicolas Houchet, executive pastry chef at the Savoy, joins the team for the semi-final of Britain's toughest patisserie competition. The four remaining teams must perfect Nicolas' modern version of the peach Melba with a minimal recipe to guide them. For their second challenge, the teams create an entirely edible fairy-tale scene with hidden rhubarb and custard desserts to serve 40.

The final of Britain's toughest patisserie competition, hosted by Ellie Taylor and Liam Charles, with judges Benoit Blin and Cherish Finden. The remaining three teams create an Afternoon Tea display and make a banquet celebrating the very best of British, with towering sugar and chocolate showpieces and enough desserts to feed 120.
