1 recipe for Double-Crust Pie shell (if you don't have one, let me know), homemade is better than store bought.
5 cups blackberries
1 cup sugar
1/3 cup flour
1/2 tsp ground cinnamon
Roll out pie crust and place half in 9 inch pie plate. In large bowl mix berries and sugar and flour. Pour into pie crust. Cover with top half of crust, seal edges, slit top, sprinle with milk and sugar. Cover edge with foil. Bake at 375 for 25 minutes (50 minutes if frozen berries are used). Remove foil. Bake additional 25 minutes or until filling is bubble and pastry pie is golden. Cool or wire rack. YUM!
