I made my first cake this week- and I was pretty happy with it! I finished it Saturday afternoon and put a few sheets of saran wrap over the cake, but they were loose- not tightly wrapped. When I got home from Church Sunday morning, and removed the wrap, all of my black polka dots had bled pink onto the white icing! Ack...
I pulled off all of my dots and re-did them with larger spots. Luckily I had put all of the icing in the refrigerator just in case I needed to make a repair.
Does any other icing bleed? This was a pre-mixed BLACK food coloring that I purchased from a cake supply store.
The good thing was the cake tasted great, and quite a few people asked me where I had bought it. Very satisfying!
Normal. All dark colors will bleed/stain. No need to wrap the cake at all.
