Shop Colour Mill Oil Based Pigment Coloring which outperforms conventional gel coloring. Use this quality food + candy coloring in chocolate, candy melts, almond bark, cake batter, icings and frostings. This special food dye works so well because they've removed all water based materials, replacing it with bake & cake friendly oils, these oils mix through much better than water-based gels (which we know water repels from the oils in your baking). On top of this, their colors are put through a specialized micro-milling process to create a color which is both grain and streak free. These micro pigments allow the coloring to mix through more effectively, meaning you'll get less uneven or speckled results.
