In the articles that I have been reading, they will refer to using gumpaste for some items and fondant for others. I also see referenced putting an additive into fondant to make it harden. Is there a rule of thumb for when I need to use fondant for creations or gumpaste and what is this hardening agent?
Hi Terri, you've posted in the Global Sugar Arts forum..so that's why you're not getting responses.
Here's a simlar post:
Fondant is used when you want to eat the finished product like on a cake, molding something, lace pieces for a cake. etc. Gumpaste hardens like a rock when dry and does not taste good. Use gumpaste for making flowers. You can mix the two together for molding pieces, making letters cutouts,etc.
The ingredient added to fondant to make it hard like gumpaste is called Tylose.
I hope this helps.
