Ingredients

• 0.25 cups butter
• 1 tablespoon all-purpose flour
• 0.5 cups white sugar
• 0.5 cups brown sugar
• 0.25 cups water
• 1 teaspoon lemon juice
• 1 , 6 ounce
• 1 , 14.1 ounce
• 4 large Granny Smith apple - peeled , cored, and sliced

Instructions

1. 1 Preheat the 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 white sugar, brown sugar, water, and lemon juice into butter mixture. Bring to a simmer, whisking constantly, until sauce 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 1 pastry crust. Place apple slices and remaining blackberries into crust. Cut remaining pastry crust into strips, about 1-inch wide. Use strips to weave a lattice top over apple-blackberry filling; pinch ends of strips to edge of bottom crust to seal. Spoon hot blackberry sauce over pie, letting it soak through the openings in top crust. Place pie onto a baking sheet.
4. 4 Bake in the preheated oven for 15 minutes. Reduce oven temperature to 350 degrees F (175 degrees C) and continue baking until crust is golden brown and sauce is bubbling, 35 to 45 more minutes.
