Excellent photos! That is certainly the most ornate kolach I have seen. And God bless the suffering Serbs of Kosovo.
Another special bread that I love is the Greek tradition of the Vassilopita (Basil's bread) that the Greeks make for St. Basil's day (January 1.)
A gold coin is baked into it, and if your slice has the coin, this is a great blessing. I got it one year!
Well, now that I think about it that year had a lot of trials and tribulations, so maybe it wasn't exactly the kind of blessing I was expecting, but it was still great fun to get it...
