I have a square fondant cake due next weekend. It is white with black fondant circles on it. The border is made up of balls of fondant. I am airbrushing them black. I need to know how long I need to let the fondant circles and balls dry before putting them on the cake. Also, what do I need to use to attach the fondant circles to the cake? Thanks

Depending on the humidity in your area and the amount of food coloring, I would give it a good 24 hours for a semi-tacky - workable finish. May I ask why you are not just using pre-colored black fondant? The reason why I am asking is I only pull out my spray brush is when I have large jobs. But this is just me......

Regarding attaching them - - - are you appling directly to fondant or BC, with fondant I use egg white and with BC I use a bit of water if the BC has crusted.

Thanks for your response. I bought an airbrush about eight months ago and I haven't used it yet. I wanted to try it on this cake. I will be using a mmf recipe. I read somewhere that using black fondant will turn their mouths black and the airbrush will not. Or at least not as bad. Don't know if it's true or not.

I agree I give mine overnight at least... I airbrush my trims a lot because I like the color depth I get with the AB.... good luck!

Oh sure, black fondant will turn a mouth color, any strong color will do that, blue, green, etc. But in small amounts it's not a big deal.

But I certainly understand why you want to try out your sprayer!
