You can tint your icing almost any shade with this set of 8 icing colours set. The gel-based icing colour gives you a bright, rich colour that won't ever change the consistency of your cake batter, buttercream or royal icing. You can also use it to tint white fondant and gum paste. You'll find a rainbow of colours, ready to blend together for creating your own custom shades. Instructions for use: use a cocktail stick to take some colouring from the jar. Use a clean stick every time you add more colouring and wipe it on your marzipan or fondant. For a deeper colour, simply add more colouring. Knead well to colour evenly, knead less for a marbled effect. Make sure the colouring stays in the middle of the mass to prevent your hands getting covered in colour. Wash your hands with warm water and soap to clean the colour off your hands.
