From Kerasma's Food & Wine: An Odyssey Special Report. "The ubiquitous tyropitta bears little resemblance to the dizzying variety of savory and sweet cheese-based Domokou and honey pies popular throughout Greek regional cuisine. In this version, from the Cycladic island of Folegandros, the filling is flavored with onions–almost as strong a presence as the feta–and encased in a thick bread crust. Kalasouna was traditionally made on Saturdays, the same day on which bread was baked, since the shell was made from a piece of the leavened dough to which some olive oil was added. This version is slightly simpler, but as tasty." Prep time is a guess.
