I don't. Were I in charge of Xmas dinner it'd likely be a lot better than most years. And I suspect I would do very little in advance save for, perhaps, preparng the veg the previous night ready to put on. Can't think of much I'd want pre-prepared in the freezer. Traditionally, in our family, lunch is late on Xmas, and so folk wait until it is done, supping their favourite tipple or drinking coffee/tea, amusing themselves with their Xmas gifts or watching the TV. That said by brother's woman did the honours last year, and did very well indeed.
