This is the Rainbow Trout Cake I've made for my uncle, Jean, who loooves to go fishing. No need to say how happy and surprised he was when I showed him the cake! It is a carrot cake with vanilla buttercream icing. I covered it in white fondant and painted it with gel colors. The green is a mix of Welton's ''Moss Green'' and ''Brown'', the pink is a mix of pink colored powder with a little bit of Welton's ''No Taste Red'' and black spots.
