Can Royal Icing be piped onto Crusting buttercream?
I have a cake this weekend and the client wants black royal icing (scroll work) on a bright white cake. Can this be done or will the RI melt and bleed black colouring onto the buttercream.
Please any tips?
Yes it can be done on buttercream with out it melting. Just don't close the cake up in an air tight container.
As far as bleeding, I'm not sure.
