Pecan Pie Pockets
In a Dutch oven or deep fryer, heat the oil over medium heat to 350 degrees F.
On a lightly floured surface, unroll the pie crust. Cut out rounds using a 4 1/2-inch cutter. Re-roll the dough as needed. Repeat the procedure with the remaining dough. Place 1 pie crust round on a clean, flat surface. Lightly brush the edges of the crust with the beaten egg yolk. Place 1 heaping tablespoon of pecan mixture in the center of the round. Fold the dough over the filling, pressing the edges with a fork to seal. Repeat with the remaining rounds and pecan mixture.
Fry the pies in batches until lightly browned, 1 to 2 minutes per side. Drain on paper towels. Lightly dust with confectioners' sugar, if desired.
