Everything! What's the best way to keep gum paste from sticking to your rolling pin/counter/anything else it comes into contact with?
I was told to use shortening but I still find it sticks to the counter and has to be really gently scraped off. What about icing sugar?
I use icing sugar all the time. Shortening is too greasy for me but it's personal choice really. You don't need to drown your work surface in icing sugar in order for it to work for you. Give it a go and see what happens.
Cornstarch! Works like a charm for fondant and rolled buttercream, so I'm quite sure it will do the same for gumpaste.
I always use a marble cheese board to work on with a very small amount of crisco.... no problem with it sticking... if a small amount gets left on it clean it off or it will dry and cause the next to stick.
I use cornstarch in molds.
Cornstarch!! It's awesome. I use it for gumpaste and fondant.
