KOŁDUNY, ANYONE?

Anyone ever had kołduny, a type of pierogi from the Polish-Lithuanian borderlands filled with miced raw lamb seasoned wtih garlic and marjoram. These are served in a bowl of hot broth.
How about lentil-filled pierogi -- a speciality of NE Poland's Podlasie region?
Both are very nice but not too widely known outside their traditional stomping grounds.

Actually kołduny taste almost the same as mok-mok, which are Tibetan dumplings served in broth which I had the luck or chance to try once in the Himalayas way back in the early seventies as a child. I mean - my parents bought the broth for me to eat, I didn't go there alone ;-)
