To color frosting, add a little jam instead of food coloring.
Simple and healthy =)
Well, healthier than the strange things that food coloring is made of =)
So, I tried this trick. I added 2 Tbsp. boysenberry jam (just fruit and sugar) to my recipe. It didn't color it enough though. I could just taste a hint of it. I suspect there are jams that work better than others. I put in 2 drops of food coloring with the frosting to finish it off.
I am going to try it again, though, the next time I have a jam open that is red in color.
I wonder if it made a difference that I used healthy jam! =) Go figure.
