It's the semifinals, meaning that it's down to the final four, who will be dealing with patisserie this week, they needing to produce items attractive, glamorous and sophisticated enough for a Parisian patisserie window display. The four are asked to make a layered mousse cake for the signature challenge, twelve identical iced fingers apiece for the technical challenge, and a selection of three different types of pastry for the showstopper challenge, with the caveat that all three must use the same dough adding an extra layer of complexity in the different bake times stemming from the fillings they use for each. This last challenge will be an unusually long one in the dough needing to rest in the refrigerator for twelve hours before shaping. At the end of these three challenges, one will receive arguably the most difficult news in the competition of not moving on to what will be the finale. Interspersed with the bakes, Mel and Sue learn about the history of patisserie in Britain, and the history of arguably the most famous "French" pastry, the croissant.
