Royal Icing

Directions

1. 1
   Combine all ingredients in the bowl of an electric mixer fitted with the paddle attachment.
2. 2
   Mix on low speed until smooth, about 7 minutes.
3. 3
   If icing is too thick, add more water; if too thin, beat icing 2 to 3 minutes more or add more confectioners sugar a tablespoon at a time.
4. 4
   Use icing immediately, or store in an airtight container up to 2 days (icing hardens quickly when exposed to air).
5. 5
   Beat well with a rubber spatula before using.
