This recipe was published in "Treasury of Holiday Cookies", one of those cook booklets you get at the grocery. It caught my attention due to the pistachio farm that we frequent in NM. They sell wonderful pistachio cookies. I haven't made this as yet, but plan to for the holidays. The recipe in the book calls for ¼ cup freshly ground nutmeg; however, I felt that might be a tad overpowering. I did adjust the nutmeg to ¼ to ½ teaspoon. Feel free to use more if needed.
