At one time I spent the holidays in the UK as part of a previous bf's family and I always hated the stupid little sausages wrapped in bacon as a side dish. Never got the appeal of brussel sprouts either.
My aunt and uncle lived in the UK in the 70s and brought back the whole christmas cracker thing, so my family has always more or less done that. We also open Santa gifts in the morning, and family presents in the evening as a tradition.
Now, however, we have to take the Swedish bf's traditions into account, if we are in the US or Sweden. My family asks him to make Swedish meatballs for the dinner table, and bake certain traditional cookies. Krispbrod makes it to the table too. If we are at his parent's home, then EVERYONE in the entire country sits down at 4.30 in the afternoon of the 24th or so to watch Kalle Anka (Donald Duck) and a bunch of racist old Disney cartoons broadcast on the primary state channel, before watching the King's address and then eating dinner before opening presents in the evening as well. Dinner has to involve Jansson's frestelse on the side - some awful dish of sardines, potatoes, cream, and breadcrumbs. Usually either venison or moose makes it to the table in addition to ham, though one year we also had wild boar. Lots of sausage, cheese, chocolates, with pickled herring and boiled potatoes to start. Special booze too - lots and lots of cold Swedish snaps taken in shots throughout the meal. By the time we get to presents everyone is pretty hammered and frankly, I don't actually remember what we have for dessert.
This year we are on our own for the first time and its all a little weird. So I am guessing we will mash everything together best we can. Get in some beef wellingtons from the butcher. Roast some potatoes and try some sprouts on the side. Put out the special package of Christmas krispbrod and some pepparkakor and cookies and snaps from the Swedish bakery/shops in town. Maybe I will get in a pudding, but I don't like fruitcake in general. We will probably open gifts in the evening as usual and then after that who knows - maybe watch a movie.
