This classic dessert gets a Christmas & New Year's twist with eggnog flavors and an opulent-sounding presentation. Start making this, one day before serving. It sounded so good that I posted this before trying. Courtesy of epicurious.com, which was found in Bon Apetit, December 2003. Did not include chilling times. If you don't make the chocolate leaves it will not hurt the integrity of the trifle.
