I read the previous reviews of AmeriColor's Super Black icing coloring and decided to give it a try to make my daughter's zebra-striped birthday cake. I wanted a black that I could use without having to start with chocolate icing (birthday girl does not like chocolate!). It turned snow-white marshmallow fondant BLACK, with very little of the gel and no noticeable taste difference. I was afraid that the coloring would leave my hands purple or blue, but the only place I noticed a stain was where I touched the full-strength coloring directly--once I mixed it in with the melted marshmallow before mixing the powdered sugar in to make the fondant, there were not problems with stains. I can't say if it would stain stone counters, though--I was not brave enough to test it on my granite, and so I kneaded the fondant on wax paper. Like other reviewers, I was a Wilton fan for years, but love this new alternative and will definitely be using AmeriColor from now on.
