Recipe : Blackberry-Lemon Pie

Ingredients
1 recipe pastry for a 9 inch double crust pie
3/4 cup brown sugar
1 tablespoon lemon zest
4 cups fresh blackberries, rinsed and drained
1 cup white sugar
1/2 cup all-purpose flour
1 tablespoon lemon zest
1 tablespoon butter

Directions
Preheat oven to 350 degrees F (175 degrees C).
Place bottom crust into a 9 inch pie pan. In a medium bowl, crumble remaining pie crust into a bowl with the brown sugar and 1 tablespoon lemon zest. Mix with hands until dough becomes pea-size crumbs. Set aside.
In a large bowl, combine blackberries, white sugar, flour and 1 tablespoon lemon zest. Fill bottom pie crust with blackberry mixture. Sprinkle crumb topping over mixture and dot with butter.
Bake pie in preheated oven for 45 minutes to 1 hour, or until crust is browned and berries are bubbling. Let stand before serving.
