My mother used to make "pecan sandies" every Christmas. They were crescent shaped cookies with pecans and really did melt in your mouth. I have purchased many cookies over the years since she passed, trying to find something that came close with no luck. These "David Meltaways" are so close to my mothers that when I ate my first one I was hit with such a wave of nostalgia that I literally cried. This has really made my Christmas to finally find the "perfect" cookie my Mom used to make.
