I have made these cookies every Christmas since 1977, which qualifies them as a Family Tradition. They require two separate doughs, but it's well worth the effort. The yield is very large -- 70 cookies -- I usually bake half and leave the other half in the freezer until Christmas Eve. They also taste best if they've been left to age a day or two. This recipe requires one large loaf pan, two small loaf pans, or a square (8x8) cake pan with straight sides. I prefer the square pan. Whatever you use, you need to line the pans with aluminum foil or waxpaper so that you can lift the dough out after it freezes.
