Mel takes a shift at a London Turkish bakery making baklava, and she discovers the history of this delicate desert that hailed from the palaces of Sultans.And finally there is a bite-size showstopper, a fine pastry which notoriously difficult to make and even trickier to bake. Which bakers will impress Mary and Paul enough to keep their place in the tent, and who will be heading home?
