Can yo u freeze fondant and gumpaste ?
if you freeze it, then it gets super, duper hard. Popping it back in the microwave will eventually cause it to crack and dry out.
Keep it in an airtight container.

I was trying to purchase some in a large bucket so I would not have to order anymore anytime soon and just wanted to know the best way of keeping or storing it for some period of time, I did not want to waste my money and it gets hard.
