Kicking off the series, Jo is joined by Roisin Conaty, Paul Rankin and Gregg Wallace to discuss the 12 new bakers and their bakes. The theme this week is cakes. What do the panel think of the bakers' Swiss roll? And how did they fare with their first ever technical challenge - Mary Berry's cherry cake? Whose 36 miniature cakes stopped the show? Plus lots of 'exclusive' footage from the tent.
