Colour Mill Oil-Based Food Colouring is a professional-grade, highly pigmented dye specifically formulated to thrive in high-fat environments. Unlike traditional water-based gels, its oil-soluble formula disperses evenly through fats and oils found in ingredients like buttercream, chocolate, ganache, and cake batter. This results in vibrant, fade-resistant, and consistent shades. The product is flavour-neutral, filler-free, and requires only a small amount to achieve intense colour.
