Pistachio and Orange Cake with Swiss Meringue Buttercream and Orange Curd
When Amelia returned to the Celebrity Bake Off tent, she carried the memory of an earlier disappointment. For her Showstopper, she chose redemption through ambition: a sophisticated pistachio and orange cake with multiple components requiring precision timing and technique. The architecture was impressive: tender pistachio sponge layers perfumed with orange, filled with silky Swiss meringue buttercream and tangy orange curd, all enrobed in glossy chocolate ganache with elaborate piping that demonstrated both confidence and skill.
