Blackberry Pie II

Ingredients

• 4 1/2 cups fresh blackberries, rinsed and drained
• 1 1/2 cups white sugar
• 1/4 cup tapioca flour
• 1 recipe pastry for a 9 inch double crust pie
• 1 egg white, beaten
• 1 tablespoon white sugar

Directions

Mix tapioca flour and sugar together, and blend mixture into the berries.

Line a pie dish with pastry. Pour filling into pie shell, and cover with top crust. Seal edges by pinching or fluting the edge. Brush top with egg white and sprinkle with a little sugar. Cut slits in top to allow steam to escape.

Bake at 350 degrees F (175 degrees C) for 30 to 40 minutes, until pie is golden brown and bubbly.
