The Great British Bake Off is back and joined by An Extra Slice on BBC Two. Jo Brand is joined by comedian Josh Widdicombe and chef Rosemary Shrager to dissect the latest goings-on, with unseen footage and an interview with the latest baker to leave the tent. It is biscuit week, so Jo and her guests celebrate all sorts of biscuits, tasting audience attempts at gingerbread and garibaldis and looking at viewer photos of their bakes from home - the good, the bad and the down-right disastrous. What does Jo's panel make of the remaining 11 bakers and their attempts at decorated biscuits? Mary Berry's challenging technical? And which baker's 3D biscuit creation most impressed in the showstopper?
