Finely grated orange zest and ground cardamom lend lovely wintry flavors to these Italian biscotti, which are also studded with dried cranberries and sliced almonds. Be sure to remove the log after the first baking when it is just starting to take on color and is still soft to the touch, otherwise it will be too hard to slice without crumbling. Also, use a serrated (or bread) knife to slice the log, using gentle sawing motion.
