Apple Blackberry Pie

Directions

1. 1
   Preheat oven to 425 degrees F (220 degrees C).
2. 2
   Melt butter in a saucepan over medium-low heat; stir in flour to make a smooth paste. Whisk water, white sugar, brown sugar, and lemon juice into butter mixture. Bring to a simmer and whisk constantly until mixture is thick, about 3 minutes. Stir 6 blackberry halves into sauce, reduce heat to low, and continue cooking while you complete remaining steps. Stir sauce occasionally.
3. 3
   Line a 9-inch pie dish with a crust. Place apples and remaining blackberries into crust. Cut remaining crust into strips about 1 inch wide. Weave pie crust strips into a lattice crust on top of the pie; pinch ends of strips to edge of bottom crust to seal. Spoon hot blackberry sauce over pie, letting it soak through the openings in the top crust. Place pie onto a baking sheet to catch drips.
4. 4
   Bake in the preheated oven for 15 minutes. Reduce oven heat to 350 degrees F (175 degrees C) and continue baking until crust is golden brown and sauce is bubbling, 35 to 45 more minutes.
