So, I have a 3 tier wedding cake, white iced buttercream with BLACK scroll work on the sides. Very pretty design... bUTTtttttttt .....
I'm worried about the balck running. I could do it in royal and then paint it with luster dust. Do you think that would help any. Little more work but I would not mind if it all came out good in the end.
AND If it does run, how can I fix that on site???
A good butter cream made with shortening like indydebi's should do well in the heat, or you can make it with the royal like you suggested.
