How fun is this! I usually shy away from using plain old vanilla icing but if I could make all these awesome colors with just your basic food coloring set, I would love it! They tell you exactly how many drops of each color you need to get the perfect color. My daughter and I love making cupcakes so we will have to try this out and let you know how it goes. This came from the May issue of Food network magazine and I heard about it thru Oh the lovely things blog. If you love cupcakes ( and who doesn't) you gotta try this too. Let me know how it goes.
