Christmas cookies... when my boys were little I made edible ornaments out of cookies, candies, etc.... to hang on the tree. That way I never worried about glass ornaments breaking and cutting their hands, etc... there are tons of cute ways to make an edible decor for your tree.
Polish rogaliki mean "little horns" because of their shape. There are many versions -- some recipes require rolling the dough and cutting it into triangles, adding a dollop of filling and rolling, like Jewish rugelach. This recipe is for a hand-formed cookie similar to Polish Christmas Crescents, described in 1., above, except these are made with almonds. They melt in your mouth.
