Host: "For your semi final signature challenge, the judges would like you to bake eight patisserie style layered slices. Your layered slices need to be identical, and when cut into, they should hold their form, displaying those beautiful layers. The judges will be looking for technically flawless, high end bakes."

Prue Leith: "I love patisserie week because it gives the baker the chance to show how skillful they can be. We're asking for eight identical layered slices."
