of confectioner's sugar
pasteurized egg whites
of vanilla extract
food coloring gel
NOTE: Please make sure you use pasteurized egg whites and NOT raw egg whites. Pasteurized egg whites are available at most grocery stores in a carton in the egg section.
I find that food coloring gel is a better choice because it's more concentrated and will not impact the liquid level of the icing.
Combine the egg whites and vanilla in a mixer and beat until frothy.
Gradually add the confectioner's sugar until it's fully incorporated and the icing is shiny.
Keep beating until the mixture forms stiff, glossy peaks.
