Light and flaky filled cookie. One of my mother's dear friends, a woman of German heritage, shared this recipe with her more than 40 years ago. At the time, it had been in her family for more than 100 years! It has always been my favorite cookie for special occasions and still is. We use two variations for the filling: the traditional orange date nut filling provided here or, mincemeat, a family favorite, during the holiday season. The filled cookies freeze well and can be baked off straight from the freezer. For best results, be certain that the dough is thoroughly chilled before rolling out and that the filling has cooled completely before use.
