I made some fondant flowers and set them out to dry. When I went to use them they kept breaking, why does this happen? Do I need to add something to the fondant/gumpaste?

what were you trying to do with them? I just recently found out that if you want to wire them, you need to set them out for about 15 minutes to firm up, yet still be workable then start wiring immediately or they snap like dry kindling!!

I was making daisies.

What does Tylose powder to?

use tylose in fondant to make it harder/sturdier for modeling figures etc..

I was asking if you were using the daisies directly on the cake or were trying to make them sturdy for wiring.

if you are using them directly on the cake, then add a little corn syrup to keep them firm but pliable so you can attach them to the cake without them breaking.

I set them out to dry for several days.
