Well, the answer is obvious; make your Christmas Cake.
I tend to keep well away from the kitchen when such operations are in progress. I believe that Lady M used Mary Berry's 'Classic Rich Christmas Cake' recipe. I've just had a look at the page, and the list of ingredients is staggering. It took 4½ hrs in the oven.
Yesterday was my shopping day, and Lady M asked me to look out for cake decorations (Santa, Reindeer, Tree, Crib, Sheep, Elves, etc), but France has no tradition of either rich fruit cakes or small plastic Yuletide figures, so we'll have to search around for our old ones. Normally they sit atop a covering of Marzipan, sprinkled with Icing Sugar (snow).
Christmas cake is rather like Christmas Pudding. You really look forward to them, but when the time comes, you're usually stuffed with Turkey or Goose.
She's also started mentioning the word 'tree'. Personally I wouldn't have one in the house before about the 15th (later if possible), but her excuse is that the children will have so much fun decorating it.
I think they'd have even more fun decorating on the 15th.
The cake is now resting in a large Le Creuset pot, and having it's bottom anointed with Armagnac every few days. It should be ready for eating in a couple of weeks; unless we can't resist.
