Inasmuch as I don't do a turkey every week, that will be an event, complete with my Dad's stuffing, which IMO is unbeatable -- and my garlic mash, likewise -- and whatever veg calls to me from the fresh produce, as well as the rest of the trimmings. We abandoned the Christmas Pudding years ago, because it's just too rich after that big meal, so every year it's something different for dessert, and I'm still tossing around possibilities.
That will all happen on Boxing Day, actually, as "number one son" will be with his Mum for dinner on Christmas Day. However, he will join us earlier in the day for The Tree and probably for brunch, which will likely be Eggs Benny, the House Special for Special Brunches.
Other than that, I don't do a lot of Holiday Cooking/Baking, because it's mostly just the two of us, with one or two added here and there, which does not add up to enough mouths to consume all the calories safely.
The pounds go on all too easily, and then take dynamite to get them off.
