It's a celebration for those on restricted diets either by choice or necessity in that all three challenges center on one food restriction or another. It's dairy-free for the signature, this challenge made all the more difficult in that one component is traditionally front and center "cream" in they asked to make eight ice cream sandwiches apiece. While they have to find cow's cream and milk alternatives for that ice cream component, their choices especially important in wanting that familiar ice cream mouth feel, they also have to find a butter alternative for the cookie component. It's meat-free for the technical in they asked to make eight vegan sausage rolls apiece accompanied by a chili onion chutney, Prue, the challenge setter, at least providing them with the necessary ingredients for the faux sausage and the butter substitute of vegan block for the pastry. And it's gluten-free for the showstopper in each making a minimum two-tiered celebration cake. The primary issue is to find alternatives for gluten to act as the structural component for the cake sponges themselves, gluten, traditionally in the use of wheat flour, that item which generally holds most cakes together preventing them from falling apart under their own weight or crumbling to pieces.
