Making the Glazy Top:
In a medium bowl, combine the confectioners’ sugar, orange juice and food coloring. Mix until smooth. Spread the glaze over top of cake, allowing the excess to drizzle over edge. Let glaze set, about 15 minutes.
Chef’s Tip: Easiest frosting of cakes is done by placing the cakes in your desired frosting dish, and refrigerate the cakes for at least 1 hour. I will often do mine for about three hours, or even overnight.
So, the following morning you can dust off anything extra crumbs, and frost with room temperature frosting. Because of the stiffness of the cake, it will not crumb out using this method.
Crumb out means that when you are frosting some of the crumbs of the cake get into the frosting, and sometimes the top part of the cake will also come off will you are trying to frost. Having the cake chilled makes it more stiff, and less likely to crumb out.
