Hello - I saw on one of the cake television shows a technique I had not heard of before and wanted to see if anyone here has tried it and if so, did it work. After putting fondant on a cake, the lady took her airbrush gun and sprayed the cake with vodka, then she painted it. The rationale for the vodka was to remove any cornstarch that may have been left on the fondant, making for a clean surface to airbrush on. Any thoughts on this? I'd love to try it but hate to risk ruining a cake if it causes any sort of issues.

Why don't you triy it on a lg piece of roll out fondant or a fondant covered dummy cake or you can cover one of your cake pans with fondant and try the technique. Let us know what happens I do not have an airbrush, but I am thinking of buying one!

It's true - most cakers don't have an airbrush so you can just paint it on, leave it to evaporate.

I prefer everclear, the higher the proof of the alcohol, the faster it evaporates.

I don't have an airbrush either. I paint the vodka on with a large brush when I want the cake to have a slightly shiny finish. It makes the colors look more vibrant too.
