How to make Fake Display Mochi?

[dude102]

How do you make display mochi that is based off a real mochi? I want to preserve an ice cream mochi so that it wont spoil or change color. How is this done? Do I need some kind of wax?

Gum paste and/ or fondant might work.

I suspect you could make some with modeling clay.
