Frequently Asked Questions

Is oil-based food colouring different from water-based?

Yes, and the difference matters significantly for fat-based products. Water-based colouring causes chocolate and candy melts to seize (turn lumpy and grainy) because water and cocoa butter don't mix. Colour Mill is oil-based, so it integrates smoothly into chocolate, candy melts, and fat-based buttercream without any seizing or splitting. For products like chocolate bark, cake pops, and ganache, oil-based colouring is the only type that works reliably.

How much Colour Mill Oil Based Colouring do I use?

Colour Mill is highly concentrated, so start with a small amount — typically 2 to 5 drops per 100g of product — then add more gradually until you reach the desired shade. For deep, intense colours (such as dark navy or black), you may need a little more. Always mix thoroughly before adding extra colour. One 20ml bottle goes a very long way for most home bakers.
