Most home cooks in Greece did not use the store bought thin sheets of phyllo, but they made their own, called horiatiko phyllo (village phyllo). A thick, crunchy phyllo made with olive oil. It is not an exact recipe, many cooks provide directions that are usually vague as everybody has their own recipe, which they have perfected. I have managed to figure out almost exact amounts for a great result.
This phyllo can be used for almost all pites (Greek pies) that one makes in a pan. There is no butter, so it is a crust that can be used in vegan recipes as well. Make sure the olive oil you use is fresh, stale olive oil will give off a bad flavor. I also add varying amounts of whole wheat flour, for a different texture and added fiber.
