As we said before, Christmas Day is much too hot for anybody to be sweating it out in front of an oven. The traditional Christmas ham in Australia is usually made a couple of days in advance and then chilled before being served. The situation is the same with the main dish, turkey. Everyone eats as much as they can, and your Uncle Ben can generally cram in thirds or fourths of anything he's served. It is that good! Nevertheless, there is usually enough left over, allowing you to eat it in sandwiches for the following month. And it won't be a problem for you at all since it's mouthwateringly good.
