Preheat oven to 425 degrees Fahrenheit. For the crust, mix flour and salt and cut in shortening (cut into tiny pieces using two knives until it resembles coarse crumbs). Add orange juice. Gently combine by hand until it forms a ball. Divide in half and roll out one piece on a lightly floured board, into a circle about half an inch bigger than your pie pan. Fold over, lift, and ease into pan. Trim off hanging edge.

Combine all filling ingredients except margarine. Place in pie crust. Dot top with small pieces of margarine.

Roll out second half of dough. Fold over and place in pan on top of filling. Turn edge of upper crust over the edge of the pie crust and under the lower crust to seal edges. Flute edges by pressing down firmly with a fork or your fingers to seal the crusts together.

Cut slits into top crust to allow steam to escape during baking. Sprinkle sugar and cinnamon on top. Place pie on cookie sheet to catch spills and bake in preheated oven for 45 minutes.
