I married a third-generation Slovak, and have learned a number of Slovak words and traditions over the years. It's pretty interesting for someone like me, who has no strong ethnic heritage (being an American "mutt").
My wife sent me on a mission yesterday to acquire a traditional Slovak Christmas food, "Oplatky". I called over to our local SELC church (also Missouri Synod Lutheran, but with a Slovak heritage). They make a certain amount of the stuff each year, and sure enough they had just one order left!
Check it out - I think it's a nice tradition. In my wife's family, they eat the oplatky drizzled with honey. I understand Pentecost also uses the oplatky as communion wafer throughout the year.
