Cake made for my son's 5th birthday. I followed a tutorial by Fancy Topcake.to make the mermaid out of gumpaste. My son said he wanted a shark swimming around the mermaid's island, and when I sketched plans for the cake with only a shark's head and dorsal fin emerging out of the cake base he shook his head and insisted he wanted a WHOLE shark. I figured the only way to do that was to embed the thing in Jello. After some experimentation I determined gumpaste would not work as over time it dissolves in gelatin, but modeling chocolate remains intact with minimal color bleeding. I went ahead and made some gumpaste starfish to go in the "water", though, as the slow dissolving made for an interesting effect on something that didn't have to stick out partway.
