Hi. I am making a halloween cake in the shape of a couldron. The cake was made in a semi-hemispherical metal bowl and has turned out well. I'm just about to start ganaching it. The bottom two layers are obviously quite a bit narrower at the bottom than the top so I'm not sure how to get the fondant to stick to it. I thought about decorating it upside down to start with on an 8" board which is the size of the bottom of the cake. But I don't actually want to ice the bottom as it will later be turned over and put on an iced cake drum. If I do do it upside down and just do the sides then I am still going to need to turn it over and decorate the top of it separately. I think??? I'm wondering, when I turn it over to decorate the top, if the fondant will just fall off as it will be defying gravity if you know what I mean?
How would YOU go about icing the sides and top of a half hemispherical cake?
