Re: where can i buy a Goldspray to decore a cake..
I saw this at the Globus in Neuchatel. Maybe your local Globus has it as well.
It was in with all the baking stuff. At the Neuchatel Globus this includes tools as well as some food (decorator sugar, color sprays, chocolate, spices, etc) items. Not sure how your Globus is set up, so sure if in other Globuses "food" and "equipment" are separate.
