We have Christmas dinner in turn at my house, DD2 and DS. DD1 lives at the other end of the country, and spends Christmas with the other inlaws, so her contact is by phone. This year it will be at DS. DiL will probably cook a couple of kosher chickens, as kosher turkeys seem to be in short supply. Actually, kosher meat of all kinds is as rare in Edinburgh as the proverbial pork chop in a synagogue, and previous Christmas birds have come from Glasgow or Manchester. She does a mean Christmas lunch, with the trimmings, despite not sharing the religious aspects of the day.
When it is here, everyone seems to be in my kitchen (drinks in hand) so they end up doing something! They ask beforehand if they can bring anything, so DD2 usually brings her famed trifle. She now makes two, one alcoholic and one not, as DiL can't drink normal sherry. I make cranberry and orange sauce, to DH's recipe (used to be his speciality) with port in one half but not in the other (for DiL)
SonIL 2 is the sprout guru - he always peels a sackful on Christmas Eve, with TV on and glass in hand, wherever the meal will be. I don't let DS make bread sauce any more, since he took "Stir it so that it doesn't stick" to mean "Beat it until it becomes wallpaper paste" BTW, soya milk makes good bread sauce if the normal stuff is running low, and a carton of soya milk keeps for several weeks in the fridge.
