I use a recipe that's kind of a combo of glaze and royal. It doesn't dry as rock hard as classic royal icing, but it's sturdy enough for detailing, plus with the flavorings I add I think it's yummy!
5 tablespoons meringue powder
¾ teaspoon cream of tartar
¾ cup warm water
2 pounds powdered sugar
2 tablespoons light corn syrup
1 teaspoon glycerin
12 drops white gel food coloring
1 teaspoon oil-free clear vanilla...
