An Extra Slice of... Biscotti

It's biscuit week, so Jo and her guests celebrate all sorts of biscuits in the An Extra Slice studio, tasting audience attempts at cookies and crackers and looking at viewer photos of their bakes from home - the good, the bad and the downright disastrous. Jo and her panel of Bake Off fans give their take on the remaining 11 bakers and their attempts at biscuits. What do the panel think of the bakers' signature biscotti? How do they think the bakers coped with technical challenge number two - Paul Hollywood's arlettes? And which baker's biscuit box most impressed in the showstopper?
