The all-lady quarter-final of The Great British Bake Off, hosted by Mel Giedroyc and Sue Perkins. The remaining five have to impress with their dessert skills. As usual starting with the signature bake, the exacting judges Mary Berry and Paul Hollywood are expecting to see and taste baked cheesecakes that reach their high expectations. Next is the technical challenge and the bete noir of most bakers, a chocolate roulade.Finally, the spectacular showstopper that requires the bakers to impress with hundreds of choux pastry profiteroles that must be perfectly baked, filled and then assembled into a croquembouche. This king of desserts is traditionally served at French weddings and Mary and Paul expect to see an impressive tower of choux pastry buns with superb flavoured fillings and held together with hardened caramel.Who will have what it takes to book a place in the semi-finals?
