Preheat and Prepare. Preheat oven to 350°F/177°C and place your pie crust pastry onto a baking sheet lined with parchment paper. Using a peeler and a sharp knife, peel, core, and chop the apples.
1 Single Pie Crust, 2 Granny Smith Apples
Combine. In a medium-sized bowl gently mix the chopped apples, blackberries, lemon juice, white granulated sugar, corn starch, ground coriander or cinnamon, and ground nutmeg.
9 Ounces Blackberries, 2 Tablespoons Lemon Juice, ¼ Cup Granulated White Sugar, 2 Tablespoons Corn Starch, ½ Teaspoons Ground Coriander, ½ Teaspoons Freshly Ground Nutmeg
Fill Tart. Spoon the filling into a mound in the center of the pie crust leaving a 2” border uncovered with fruit. Fold the crust border up and slightly over the filling. Gently press the overlapping crust to seal.
1 Egg White, 3 Tablespoons White Sparkling Sugar
Egg Wash and Bake. In a small bowl, beat the egg white with a whisk until frothy. Brush the exposed crust with the beaten egg white and then sprinkle the crust with white sparkling sugar.Bake for 40 to 50 minutes or until the crust is golden brown and the fruit filling is tender when pierced with a fork. Remove from oven, cool, and transfer the tart to a serving plate.
