Royal Icing

The following recipe is for a sweet icing
that will be used like "glue" to hold the 
house together and to decorate.  It dries 
quickly into a hard candy consistency.

3 Egg whites at room temperature
3/4 tsp of cream of tartar
1 lb. of 10x confectioner sugar - sifted

Combine in mixing bowl and mix on high
speed for 7 to 10 minutes. Beat until very
stiff - you can't overbeat. Store at room
temperature.
