Natural Blue Food Coloring
I tend to be interested in recreating conventional delights in a
totally natural way. Natural blue food coloring is one of those
super hard things to find. Most plants will give you some kind of
purple-ish color, but never a true blue.
Well, I found this article that sounds so fascinating! Anyone heard
of this flower before?
