I have never painted on my cakes, but need to do some leopard spots. Do I paint with the gels straight? Do I mix them with water, how much? I read somewhere to use Vodka, but didn't say how much and I don't want the customers to taste it! I use Wilton color gels if that makes a difference...can I paint on BC icing after it sets up??? PLEASE help!!!

vodka has no taste and completely evaporates, there is no alcohol left. It also helps the gels to dry, they are too thick to dry on their own. Thin them to the consistency you need for painting.

Otherwise on another post, someone suggested using Royal Icing to paint spots, I love that idea as well

I used the wilton gels and mixed with vanilla extract for the jimmy buffet cake in my pictures. You can paint on buttercream. Just make sure it's crusted well. I would stick in in the fridge to get nice and firm. And use a soft brush and a gentle hand. I don't think anybody's going to taste it.

Thank you for your help!
