As for myself, I hail from Norway, where the most important day of Christmas is Christmas Eve (24th), being the first day of several familiar gatherings around the dinner table (and this being our day for the unwrapping of presents).
With respect to Christmas fare traditions, Norway is divided east-to-west, whereas the Eastern part of Norway enjoy what is called "Ribbe" (Loin rib of pork).
In my part of the country, Western Norway, most people swear by what we call "Pinnekjøtt" (salted and cured mutton ribs).
...both of which are traditionally washed down with "Juleøl" ("Christmas beer" darkish, malted beer) and Aquavit (Schnaps laced with caraway and other herbs.
So - what do YOU eat for Christmas? Bring it on!
Merry Christmas to all!
