Topped with almond icing, pearl sugar and almond slivers, this classic Italian Easter cake is dotted with candied orange peel. Its batter, which is made with flour and potato starch is flavored with Strega, vanilla and lemon juice. While it is typically prepared for the spring holiday, there's no reason you can't indulge throughout the year. For authenticity's sake, you'll need to invest in a dove-shaped colomba pan.
