Emmett J Scanlan, Mark Wright, Nella Rose, Mutya Buena and Ralf Little take part in the culinary challenge, with guest judge Cherish Finden joining regulars Paul Hollywood, Noel Fielding and Alison Hammond. The contestants make Signature pull-apart savoury rolls and grapple with vegan fruit tarts in the Technical. And for the Showstopper, the celebs recreate their most ridiculous purchase ever.
