M.S.
check out www.allrecipes.com and then make a royale icing. its easy to make and use with different colors and it hardens so its not messy to eat. when your decorating the cookings you can use toothpicks to dip in the frosting and make polka dots on the cookies. and you can do marble effects with the icing as well. i use the royal icing when i do holiday cookies. the kids will have fun with it too. i usually use my fingers or a spoon to spread the icing. its fun to work with.
royale icing
3 eggwhites
1/2 teaspoon cream of tarter
1 (16oz package) powdered sugar sifted
paste food coloring works best
combine egg whites and cream of tarter in large bowl beat on medium until frothy. add half of the powered sugar, mix well. add rest of the sugar beat on high for 5-7 minutes... icing will dry hard fast so keep covered with a damp cloth. if it starts to harden on you just add a little water to it. i'v had times where it took me all day to do cookies cause i did so many and never had problems with the icing harding up on me. i just kept it covered and would add a little water every-now-n-then.
