Does anyone have any experience with vegetable-based or "natural" food colorings? My niece is allergic to red dye and, of course, my daughter wants a pink princess cake for her birthday. I am trying to find something that will make white icing pink and still be ok for my niece to eat. (I guess I could use strawberries or something like that, but was hoping to find something similar to food coloring.)
Thanks in advance!
