An Icing Sheet is a sugar based sheet that is ideal for printing on and applying to the surface or sides of a cake. It is more palatable than wafer paper.
Wafer paper is made from potato and is used mostly for accents applied to the cake. Wafer paper does not replace the icing sheet, it is just used where the icing sheet is less reliable such as when holding its shape or standing upright is important. It is also more reliable than an icing sheet in extreme humid and dry conditions.
While wafer paper is a solid color, there may be some color and texture variations. This is the nature of wafer paper. Wafer paper should not be refrigerated or frozen.
