Cover the cake with a slightly thicker coating of icing, so the comb’s ridges will not touch the cake. Hold comb at a 45 degree angle.
Choose the type of effect you want—wide or narrow—then run that edge around your cake to form ridges.Turn the turntable as you run the comb edge over the surface.
Use different combs and edges to add different contours to your iced cake.
-Comb immediately after icing the cake, while the icing is soft.
-Using a turntable helps to keep the movement of your comb smooth, so your surface will be perfect.
-Before the final icing of your cake, cover it in a thin layer of icing and allow it to chill for a few hours. This is called a ‘crumb coat’. It will keep your final layer of icing neat and free from any flaky crumbs.
