that I can use it for decorations, like flowers, etc. Will it take coloring?
It takes color very well. I've had problems with it staying put, however. I made a cake with an elaborate border, and the top border kept sliding off. I also used it on an egg-shaped cake, and the icing on the top portion of the cake started pushing downward until the whole thing looked like Homer Simpson's belly instead of a nice egg-shape. In the future, when I use this icing, I will keep the decorations light and simple. It does behave better than plain cream cheese icing, IMHO.
Yes the crusting cream cheese icing will take color. I haven't used it for flowers, but I'm sure you could as I used it for cornelli lace and borders and it was fine. You can see it in my photos, the "Princess for the Day" one. Good luck!
I've never heard of crusting cream cheese frosting until this site... what's the difference from my normal cream cheese frosting I make? Will be using for cupcakes... if that's any matter...
