Ah! Very similar to Sarma, a favorite dish of my family (Serbian) during Christmas: http://en.wikipedia.org/wiki/Sarma_(food)
My dad goes so far as to ferment his own home grown cabbage in a wooden barrel for the once or twice a year meal. From what my family tells me the original dish is thought to be attributed to the Sarmatian culture: http://en.wikipedia.org/wiki/Sarmatians hence the name...though there is no mention of that in the Wiki article.
