We're rocketing through the series, almost halfway through already! This fifth episode takes us into the world of biscuits, so make sure you stock up on snacks so you don't get hungry halfway through. I don't want to spoil any of the challenges coming up, but a quick read of the BBC suggests the Showstopper is a really tricky one! They seem to be getting harder and harder, but that's just whittling down our bakers until we get to the ultimate star baker for 2013. Yum!
