29 inchpie shells, unbaked (You can make them yourself or use bought. I used Pillsbury frozen pie shells.)
4 1/2cupsfresh blackberries
3tablespoonsbutter or margarine
Milk and 1 teaspoon brown sugar for top of crustOptional
Place bottom crust in your pie place. (Tip: I spray my pie plate with cooking spray before I add the crust. I think this makes the pie come out of the pan easier). Prick bottom crust with fork. Mix all ingredients except butter, milk and brown sugar in a large bowl with a spoon. Pour into pie shell. Cut butter in pieces on top of filling.
Place second pie shell on top and cut slits for steam to escape. Very lightly brush just a tiny bit of milk on top of the shell and sprinkle with 1 teaspoon of brown sugar. Bake in preheated 425 degree oven for 15 minutes. Reduce heat to 375 degrees and cook 20-25 more minutes until pie is brown on top. Let cool before cutting.
I think you could use frozen blackberries in this recipe, too.
