"Lemon Glaze: Mix 1 tsp. Lemon Extract, 1/3 cup hot water and 4 cups confectionrs' sugar. Drizzle over pastry, donuts or cake."
[4 cups is 1 lb. of sugar, as near as I can tell. It didn't work; that is, it wasn't a glaze, it needed more water or less sugar for that. It was a thick icing or frosting, pure and simple. I added blue food coloring to it, and used it to frost the cookies after they cooled.]
