How to Make Blueberry Blackberry Pie

Let me walk you through the steps to create this amazing Blueberry Blackberry Pie:

Make the Pie Crust

1. In a large bowl, I whisk together the flour, salt, and granulated sugar.
2. I add the very cold butter pieces and toss them in the flour until coated.
3. Using a pastry blender (or my fingertips, or even a food processor pulsed carefully), I cut the butter into the flour mixture. I continue until most pieces are about pea-sized. (It's important not to overwork it or let the butter get too warm - larger pieces are better for flakiness!)
4. In a separate bowl or measuring cup, I combine the cold water, ice, and cider vinegar.
5. I add 1 to 2 tablespoons of the icy liquid at a time to the flour/butter mixture, gently combining it with a fork after each addition. I continue adding liquid just until a shaggy ball of dough starts to form.
6. I divide the dough roughly in half. I flatten each piece of dough into a flat disk and wrap each disk tightly in plastic wrap.
7. I refrigerate the dough for at least 1 hour to let it chill and rest.

Make the Filling

1. While the dough chills, I prepare the filling. In a large bowl, I combine the shredded apple, blackberries, blueberries, fresh lemon juice, lemon zest, both granulated and light brown sugars, cornstarch, cinnamon, cardamom, cloves, and salt.
2. I stir gently until everything is evenly combined and the berries are coated.

Assemble the Pie

1. I preheat the oven to 425ºF (220°C). I place a foil-lined sheet pan in the oven as it preheats. This helps catch any drips and ensures a crisp bottom crust.
2. Using a rolling pin on a lightly floured surface, I roll out one piece of the chilled dough until it's large enough to fit the bottom of a 9-inch glass pie pan (about 12 inches in diameter).
3. I carefully transfer the dough to the pie pan and gently press it in.
4. I pour the prepared berry filling into the chilled pie shell.
5. I place the pie back into the freezer while I roll out the top pastry. Keeping it cold helps maintain the crust's structure.
6. I roll out the second piece of dough so it fits the top of the pie. I carefully place this second piece of pastry over the filling.
7. I trim the excess dough around the edges, leaving about a ½-inch overhang. I tuck the top crust edge under the bottom crust edge and flute the edges decoratively to seal the pie.
8. Using a sharp knife, I cut several slits into the top crust for venting steam during baking.
9. I whisk the egg white and 1 teaspoon of water together to make an egg wash. I brush this lightly over the top crust.
10. Finally, I sprinkle the raw coarse sugar evenly over the egg-washed crust.

Bake the Pie

1. I carefully place the assembled Blueberry Blackberry Pie onto the preheated baking sheet in the oven.
2. I bake at 425ºF (220°C) for 25 minutes.
3. Then, I lower the oven temperature to 375ºF (190°C).
4. I continue to bake for another 35 to 40 minutes, or until the pastry is a beautiful golden brown and the filling is bubbly. (If the crust starts to brown too quickly, I loosely tent the edges with aluminum foil.)

Cool Completely

1. I remove the pie from the oven and allow it to cool completely on a wire rack for at least 2 to 3 hours. This is crucial! It allows the pie filling to thicken and set properly.

Tips and Tricks for the BEST Berry Pie

Here are my secrets for making this Blueberry Blackberry Pie truly exceptional:

• Keep Everything Cold: Use very cold butter and ice water for the crust. Chilling the dough adequately is key to a flaky result.
• Don't Overwork Dough: Handle the pie dough as little as possible to avoid developing too much gluten, which makes it tough.
• Pea-Sized Butter: Aim for pea-sized (and even some slightly larger) pieces of butter remaining in the flour mixture for optimal flakiness.
• Shredded Apple: The shredded apple adds natural pectin which helps thicken the berry filling beautifully without making it gummy.
• Cool Completely: Seriously, let the pie cool for at least 2-3 hours before slicing. This allows the filling to set properly so it doesn't run out everywhere.

How to Serve

This Blueberry Blackberry Pie is classic perfection served:

• Warm with Ice Cream: A scoop of vanilla bean ice cream melting over a warm slice is heaven.
• With Whipped Cream: A dollop of lightly sweetened fresh whipped cream is also wonderful.
• As Is: Let the incredible fruit flavor and flaky crust shine on their own!

Best served slightly warm or at room temperature.

Make Ahead and Storage

• Dough: Pie dough can be made up to 3 days ahead and stored tightly wrapped in the refrigerator, or frozen for up to 3 months.
• Filling: The filling can be mixed a day ahead and stored covered in the refrigerator.
• Baked Pie: The baked pie is best enjoyed within 2-3 days. Store it covered at room temperature or in the refrigerator. Reheat slices gently in the oven if desired.

FAQs about Blueberry Blackberry Pie

• Can I use frozen berries?
  • Yes! Do not thaw the berries before using them in the filling. You may need to add 5-10 minutes to the baking time.
• Can I use a different type of apple?
  • Yes, another good baking apple like Granny Smith or Honeycrisp would work. Golden Delicious provides mild flavor and good texture.
• My pie filling was too runny. What happened?
  • Ensure you used the correct amount of cornstarch. Also, allowing the pie to cool completely for at least 2-3 hours is crucial for the filling to set properly.

Enjoy this delicious, homemade Blueberry Blackberry Pie! It's a perfect celebration of berries.
