re: Gold drip on cake

Thank you Dominique and Sandra!
Sorry I couldn’t reply earlier. I am based in India and unfortunately Rolkem super gold isn’t available over here. We do get Americolor airbrush gold, that I use for painting on cakes. Apart from this Rainbow Dust metallic food paint is available as well.
I was also thinking that its tinted white chocolate that’s then painted over. But was wondering if the above these colors will work on chocolate? Or will they sort of bead over.
Thank you once again!
