Candy coloring, food coloring, what’s the difference? Well, if you’re making colored chocolates, there’s a BIG difference! Traditional food coloring is water-based, so if you add it to chocolate, it can cause the chocolate to seize up and become a grainy mess. Candy coloring, on the other hand, is oil-based, so it can flavor chocolate with ease. Try it the next time you want to transform your truffles!
