Swiss roll
This week's theme was all things French. In the signature challenge, the bakers are challenged to make three different types of savoury canapé; Choux pastry, shortcrust or rough puff, and a third of their choice. For the technical bake, the bakers are challenged to make a Charlotte Royale; made of Swiss roll surrounding a bavarois. It is set with gelatin to form a firm dome when turned out. In the showstopper challenge, the bakers are challenged to bake an iconic French patisserie, the opera cake.
