I'm doing my first carved cake in two weeks and have a couple of questions. It's supposed to be a catfish groom's cake (similar to this one on this tutorial:  http://rosebakes.com/how-to-make-build-carve-a-catfish-cake-picture-tutorial/)...the girl from the tutorial baked a 11x14 sheet cake and she estimates the cake feeds 25-30ish. I need the cake to feed 50. So my questions are:  What size do I need to bake, considering it will be carved down? Also, what size board will it need to be on? (trying to figure out if it'll even fit in my fridge??) Thanks!!!

Can you put the carved fish on top of a sheet cake made to look like either water or a cutting board?  Then you don't have to make a bigger fish just build cake upward.  Or if the cake has to be all fish you could fit 4 - 9" x 13" cakes together to make a 13" x 18" cake.  Not sure if you would get 50 servings out of it or not.  Can you supplement with some catfish or complementary to the catfish cupcakes?
