Yes, it is the more traditional method. To make the glaze, whisk 2 cups of powdered sugar, 1-2 teaspoons of milk, and the juice of one organic lemon. Adjust the "thickness" of the glaze according to personal taste. Dip the tops of the room-temperature cookies in this glaze and set them on the cooling rack for the icing to firm up. If desired, top with colorful sprinkles.
