. Ease pastry into pie plate, being careful not to stretch pastry. Transfer filling to pastry-lined pie plate. Trim pastry to 1/2 inch beyond edge of pie plate. Fold under extra pastry. Crimp edge as desired. Do not prick pastry. Sprinkle 1/2 cup
of the flour mixture over the bottom of pie shell. Carefully pour in the molasses mixture. Sprinkle remaining flour mixture evenly over pie.
