I'm sure this is obvious to someone with any know how! I'm just making a cake for Saturday lunch time, and am wondering if I can 'compile' it now, if I do, how do I keep it. It is a swiss roll, covered in buttercream with various sugarpaste, and fairy cake creatures on it. Will everything stay fresh, and if I refrigerate it for the buttercream, will the sugarpaste get too cold? I'm very pleased with it so far, it's just in pieces! Thanks.
