I'm from Catalonia. Catalonia is a small country situated in the north-east of Spain. Catalan people usually celebrates the Christmas joining all family, taking a very special meal and singing Christmas songs, as well.
It's a very special day for all of us, principally because we meet some family members that we cannot relate with them in the rest of the year due to living far, or other reasons.
We have a special sweet food and a good drink for this celebration. The food it calls Torró (nougat). It's a very good dessert. And the drink is "cava", in France called Champagne.
I take the opportunity to wish you peace, prosperity, health and Merry Christmas.
