This is traditional Georgian recipe (and I mean Georgia as a country, not the state). It takes a bit of time and inspiration to cook, but it totally worth it.
Even though it is time consuming, with a bit of organization it can be a fun activity to do for whole family together.
I never been a big fan of lamb meat, but these dumplings taste the best made of it. However you can always substitute equal amount of beef and pork mix for lamb meat.
