The country's best young bakers go head to head. Nadiya and Allegra give four more junior bakers, Lottie, Harry, Ffion and Mehdi, the chance to compete for just one place in the quarter-finals. The technical challenge is one of Allegra's recipes for pizzetta bianchi. Which baker will achieve pizza perfection with these thin, mini white pizzas? Next the bakers have to invent a dessert in show-stopping cake form. Expect blackberry crumbles, lemon meringue pies and even jelly and ice cream to be transformed into cake.
