At Christmas time in France, a popular dish is the traditional "Buche de Noel" or "Yule log." It's a rolled cake that's decorated to look like a log, often with meringue mushrooms and greenery to represent a woodland scene. It's typically served with a side of custard or whipped cream. Another popular dish is "boudin noir," a type of black pudding made from blood and other ingredients like onions, bread, and spices. It's often served with applesauce or mashed potatoes.
