fat-soluble coloring powder
Pour the cacao butter into a saucepan and melt in on a low heat. Once melted add the white chocolate and some fat-soluble coloring powder. Mix this. Then pour it into a measuring cub and mix it once more but this time with a hand blender. Now take the chocolate ball and submerge it completely in the glaze. Let it drip for a couple of seconds and then keep it in your fridge for later.
