On a sil pad or parchment paper, lay the first layer of phyllo down and brush gently with a little of the melted butter. Phyllo is delicate and may break, but that won’t matter to the final product. Work as quickly as possible to prevent the pastry from drying out. Layer the pastry and melted butter five or six times and then sprinkle the walnut filling evenly over the pastry. Continue to layer the pastry and the melted butter until the pastry is finished, approximately 5 or 6 more layers. You don’t need to brush the top layer, but make sure you butter all the edges well, for crispiness!
