1Because phyllo is so thin & fragile, it's important to handle it with proper care. Thaw phyllo in its package as the label directs, typically overnight. If used before completely thawed, the thin sheets may tear. Once opened, use phyllo within three days.
2Work with only one sheet at a time; keep the remaining sheets covered with a damp towel. If phyllo is left uncovered it will become brittle. Brush each sheet generously with melted butter; this makes the layers crisp upon baking.
