There is a similar post just added asking a similar thing, but I am planning on glueing (royal icing) some sugar paste leaves to a fondant cake. Is there anyway to keep the petal dust from rubbing off onto the fondant. I guess it wouldnt be the end of the world if it did, I just dont want it turning into a big mess. Any input is appreciated. Thanks!

You can 'set' the dust by steaming the leaves.
Just put a pot of water on the stove to boil and pass the leaf thru the steam quickly.

A lot of steam, or just a little? Would water droplets from the boiling water hit it, or do I just hold it above the splatter? Thanks!

If you have a clothing steamer it works great for steaming fondant and gum paste.

ohhhh..good idea.... thanks!

It takes a second or two to steam your flowers. Hold it in the steam too long, and you'll melt the flower, or leaf in this case.

Steam for a few seconds just until it turns shiny and remove.

You can also dip the leaves in lacquer, but that sorta defeats the purpose of gumpaste....
