Description

In grandma's blackberry pie recipe, apples soak up the juices from the blackberries as this pie bakes in the oven — making for the perfect consistency.

Ingredients

1 egg
1 teaspoon distilled white vinegar
2 1/2 cups all-purpose flour
2 tablespoons white sugar
1 teaspoon salt
3/4 cup cold unsalted butter, cut into small cubes
7 tablespoons ice water, plus more as needed
1 apple, peeled and cut into 1/2-inch thick slices
6 cups fresh blackberries
1/2 cup white sugar

Directions

1 Beat egg and vinegar together in a small bowl; set aside. Whisk flour, 2 tablespoons sugar, and salt together in a separate bowl; cut in butter with a knife or pastry blender until mixture resembles coarse crumbs. Stir in egg-vinegar mixture. Add ice water, 1 tablespoon at a time, mixing with a fork until moist; dough should hold together when squeezed. Divide dough in half; shape into 2 balls. Wrap dough balls in plastic wrap; refrigerate 30 minutes to 3 days.
2 Preheat the oven to 375 degrees F (190 degrees C).
3 Roll out 1 dough ball to fit a 9-inch pie plate; place into pie plate and chill before baking, at least 20 minutes. Roll out top crust; set aside.
4 Arrange apple slices on bottom pie crust; scatter blackberries on top. Sprinkle with ½ cup sugar. Top pie with second crust; pinch top and bottom crusts together. Lightly brush top crust with water, sprinkle with remaining 1 tablespoon sugar. Poke several vent holes in crust with a fork to allow steam to escape during baking.
5 Bake in the preheated oven until golden brown, 40 to 45 minutes.
