I never got to the end of the video; I'm having some connection difficulties today. But it sure looked good in the preparation stage.
Our local ethnic Georgians (from the country, not the state) make them boat shaped with an egg, as I depicted my replica version. The dough is often a regular pizza dough but I think that is completely out of convenience rather than tradition. They own a pizza shop. I like it better when the dough uses keefer as the liquid, or a mix of water and sour cream. Filling is feta and mozz at about the same 60-40 ratio as mentioned in the video, but the egg is not added to the cheese filling but put into the boat when it is almost finished baking.
The version in the video looks yummy, sort of like a Parota that migrated north with some Bengali families.
Regarding the music... if you find that creepy then maybe you need to move to a more ethically-diverse area. In my neighborhood there are at least 6 different cultures represented... each with their own distinctively "creepy" music. It really does take time and patience to be able to listen to it. :)
