CAKE WITH ROYAL ICING RECIPES

Steps:

• In the bowl of an electric mixer, combine the sugar, egg whites, cream of tartar and salt. Whisk until stiff and glossy.
• To tint the frosting, divide into small bowls. Cover the ones you aren’t using with plastic wrap; the frosting dries out very quickly. Use a rubber spatula to stir in desired food coloring. Though not necessary, it makes life easier if you make two versions of each color — one that is thick to pipe the outline on the cookie, and one that is thinned out slightly with a little water to flood the outline.
• Transfer frosting to piping bags fitted with very small round tips (sizes 1 to 2 work best). Pipe frosting onto cooled cookies and let set, at least 2 hours. Or use a pastry of paint brush to decorate cookies with the frosting.

Steps:

• In large bowl of stand mixer combine the egg whites and vanilla and beat until frothy. Add confectioners' sugar gradually and mix on low speed until sugar is incorporated and mixture is shiny. Turn speed up to high and beat until mixture forms stiff, glossy peaks. This should take approximately 5 to 7 minutes. Add food coloring, if desired. For immediate use, transfer icing to pastry bag or heavy duty storage bag and pipe as desired. If using storage bag, clip corner. Store in airtight container in refrigerator for up to 3 days.
