The search for the creme de la creme of British pastry begins with Tom Kerridge welcoming three teams of expert chefs to the competition. Ahead of them lies a truly intense day of cooking in front of three of the biggest names in British pastry. Battling it out in the first heat of this intense bake off are three young chefs from a five-star hotel, a team which invents desserts for a leading supermarket and a trio of chefs who work in secret restaurants hidden away in the city of London. Judging and scoring their efforts are Benoit Blin, chef patissier at Belmond Le Manoir aux Quat'Saisons, Claire Clark MBE, world-renowned pastry chef and consultant, and Cherish Finden, executive pastry chef at The Langham, London. In the first challenge, the teams must produce three different mouthwatering patisserie items - framboisier - a classic layered slice, paris-brest - a handcrafted miniature, and a cylindrical petit gateau invented by the teams themselves. They must make 36 perfect and identical items of each pastry and with just three hours to do it, the pressure is almost too much for some. In the second challenge, the team must transform an ordinary dessert into an incredible fine-dining experience with their showpiece. For this heat, it's apple crumble and custard which gets the five-star treatment, complete with towering edible showpiece sculptures that are simply unbelievable. With heart-stopping moments, frank and uncompromising judging and cooking techniques we've never seen before, which team will score the most points and earn themselves a place in the semi-finals?
