Eastern European Christmas Traditions

One of my colleagues (and a fellow Baltic-state family lineage) shared the following article from the NYTimes about the Estonian House in NYC and their traditional blood sausage making "party" in preparation for Christmas.  As someone who has worked to learn traditional Lithuanian cooking, I'm excited to see the same attempt to pass on these culinary traditions in the Estonian-American community.  Not to mention, finding another ethnic group that uses beets as a staple in their menu is aces with me!
