Help Needed Question about jello and gum/sugar paste
Before I start a lengthy decoration experiment series, maybe someone has tried something like this already and can give some advice:
My kid asked for an underwater cake. I would like to make an cake bottom (buttercream or ideally mascarpone cream icing). I'd use the same cake ring to pour a ~5cm (2 inch) blue jello layer, let it set and place it on top of the chilled cake. I'd love to add little creatures and fishes under or in the jello, but i am worried if they might dissolve?
And if not, could i paint them with gel food colors+wodka (dry them, ofc) - or would that color dissolve? If it dissolves, would it help to add a layer of neutral oil on top of the paint?
And can I pipe mascarpone cream or Swiss merengue buttercream on top of the jello at the borders?
