Royal icing is a type of icing made with powdered sugar, water, and meringue powder (or egg whites). It may be similar to a basic icing you’ve made before, but with the added meringue powder it dries completely smooth and hardens so that you can stack and package cookies without ruining your hard work.

​

There are three main types of royal icing: detail consistency, outline consistency, and flood consistency. They are used for different decorating techniques, although sometimes you can use different consistencies to achieve the same result.

 

Some techniques may incude using a projector for writing on a cookie or using an airbursh using stencils.
