Feathering

1. Colour some white glacé icing with Dr. Oetker Food Colouring and place in a small piping bag.

2. Spread white glacé icing over your cake, and then pipe straight lines of the coloured icing across the cake.

3. Before the icing sets, draw a skewer through the lines, turn the cake round and draw the skewer in the opposite direction.

4. Continue until the top is completely 'feathered'.
