My mother made this every year for Christmas, and her daughters still do. Because it's very delicate, we have always just rolled out the dough and cut it into squares. The "edge" pieces get baked, too, and that what the cook and the kids get to nibble while the rest go in the freezer till the holidays. They're great, rich, and delicate - they shatter first when you bite them, and then melt in your mouth. Use fresh nutmeg for the best flavour.
