Leek and Celery PieAndrea Fazzari

Pitas, or savory pies, are ubiquitous in mountainous Epirus, in no small part because their portability suited itinerant sheepherding families. Even when you are staying put, this one is well worth making. Its homemade phyllo is rolled out much thicker than the commercial kind, making something more akin to a tender piecrust, and it's imbued with rich flavor from yogurt.

Cooks' notes:

· Dough can be made 3 days ahead and chilled in a sealed plastic bag. Bring to room temperature before rolling out. · Pie can be baked 4 hours ahead and kept at room temperature.
