Confectioners Sugar Glaze

2 tablespoons hot water, or milk or light cream
1/4 teaspoon vanilla, lemon, or other extracts, or
    1 teaspoon lemon juice or rum
1 cup confectioners sugar

Stir the liquid into the sugar, adding more, a few drops at a time,
as needed. The icing is of the proper consistency when it coats the spoon.
