The remaining bakers are tested to the limit in Pastry Week, including an ambitious final challenge that sees them pushed to the edge creating a majestic pie fit for a banquet. Before that, the Signature challenge centres on samosas, with a sweet and a savoury option required, and there is a classic French Technical involving two types of pastry. Paul Hollywood and Prue Leith decide which of the bakers has to leave the competition, with Noel Fielding and Sandi Toksvig on hand for some emotional support and encouragement.
