I tried adding black coloring to make the a dark black, but that didn't work - it hardened up and became crumbly..
Any suggestions or is the only alternative royal icing?
1. To color chocolate you need either an oil-based color made for chocolate or powdered color.
2. I haven't used W black chocolate, but I have used Klausen black and CK black and both are crazy black.
Wilton black candy melts are as black as it gets. I use them all the time. I'm not sure what the issue you're having is, but they're definitely black.
I agree they are black. So, I made a small batch of black royal icing and it is a lot darker black then the melts. Was trying to cut corner here, but obviously not going to work for me. I am doing stencil work on a cake and want that really deep black.
Thanks for your responses....
