i guess youll have to try it then. It will be different for sure. let us know how it turns out. I tried it once though and it was awful. I didnt use starch though.
do you have jello? maybe try putting jello on top or home made whipped cream. You might be able to do a whipped cream icing. Try searching for recipes for different types of cake toppings. And thanks for this thread, i just came up with an experiment.
