This recipe made AMAZING royal icing that went perfect on Christmas cookies. Of course, me being who I am, I was have freaking out the whole time that I was eating raw egg whites. Well, I did some research, and although it is not recommended to eat raw eggs, if you are going to it helps if they are from cage-free hens or from an organic market, since they live in healthier conditions. It is supposedly also safer to eat raw egg whites than raw egg yolks. Or if you can plan ahead, just buy pasteurized egg whites - then you are completely in the clear :)
Royal Icing
2 large egg whites or 5 tablespoons meringue powder
2 teaspoons fresh lemon juice or 1 teaspoon vanilla extract
3 cups confectioners' sugar, sifted
Food coloring, if desired
For Royal Icing:
With a hand mixer, beat the egg whites with the lemon juice or extract until frothy. Add the sifted powdered sugar and beat on low speed until combined, smooth, and shiny. Turn to high and beat approximately 5 minutes till stiff and glossy. Add food coloring, if desired, and transfer to a pasty bag to pipe onto cookies.
