Blueberry Pie Recipe

What's the difference between using fresh and frozen blueberries?

The choice between fresh and frozen blueberries can make a significant difference in the texture and final flavor of your pie. Each type has its own characteristics and requires specific preparation techniques to achieve optimal results.

Fresh Blueberries

• Fresh blueberries maintain their shape better during baking and provide a firmer texture when biting.
• The flavor is more intense and bright, with more pronounced notes of sweetness and natural acidity.
• They require less thickener since they release less liquid during cooking.

Frozen Blueberries

• They are more economical and available year-round, perfect for making pies out of season.
• They release more liquid during baking, so you'll need to increase the amount of thickener by 25%.
• No need to thaw before using; in fact, it's better to add them frozen directly to the filling.

Recipe Adjustments

• With frozen blueberries, increase the cornstarch from 4 to 5 tablespoons per 4 cups of fruit.
• For fresh blueberries, reduce sugar by 25% as they tend to be sweeter than frozen.
• Baking time may vary: frozen ones need 10-15 additional minutes.

Handling Tips

• Fresh blueberries must be washed and dried completely before using.
• Frozen ones should be kept in the freezer until the last moment to prevent thawing.
• Avoid mixing both types in the same pie, as they may cook unevenly.

Tips for achieving a perfect pie crust

Pie crust is a pastry basic that requires specific techniques to achieve a delicate, light, and flaky texture. Here are the fundamental tips for achieving a perfect pie crust.

Ingredients and temperature

• Use the highest quality butter and keep it cold at all times, you can even put it in the freezer for a few minutes before using.
• Use pastry flour with low gluten content for a more delicate texture.
• Use cold water directly from the refrigerator.

Preparation technique

• Avoid overworking the dough to prevent gluten development, which would make the crust elastic instead of flaky.
• Use the sandy method (sablage): scatter cold butter into the flour until it reaches a sand-like texture.
• Initially incorporate only 70-80% of the indicated water and adjust as needed.

During the process

• Work the dough quickly to prevent the butter from warming up.
• Don't knead to combine; just press with your hands or rolling pin.
• Use the fraisage technique: push the dough forward with a smearing motion to properly hydrate the flour with butter.

Resting and baking

• Let the dough rest in the refrigerator for at least 1-2 hours before using.
• Bake at a high temperature, ideally at 180°C (350°F).
• To prevent the base from puffing up, prick the dough with a fork and use weights over aluminum foil during the first few minutes.

How to prevent a runny or too liquid pie

The perfect consistency of a blueberry pie depends on several key factors and specific techniques to control excess liquid.

Blueberry handling

• Frozen blueberries release more liquid than fresh ones, so they need special treatment.
• If using frozen blueberries, don't thaw them before using to prevent excess liquid release.
• Wash and dry fresh blueberries completely before using them.

Using thickeners

• Increase the amount of cornstarch from 4 to 5 tablespoons per 4 cups of fruit when using frozen blueberries.
• Mix the cornstarch with cold water before incorporating it to avoid lumps.
• Cook the mixture until it bubbles and you can see the bottom of the pan, indicating it has thickened properly.

Preparation techniques

• Preheat the blueberry filling and cook it with the thickener until it thickens before using.
• Sprinkle crushed cookies or breadcrumbs on the crust base before adding the filling to absorb excess liquid.
• Let the pie cool completely before cutting so the filling can set properly.

Temperature and baking

• Initially bake the pie at a high temperature (400°F) then reduce to 350°F to ensure even cooking.
• Keep the pie in the oven until you see bubbles across the entire surface of the filling.
• Don't remove the pie from the oven until the filling is actively bubbling, indicating the thickeners have fully activated.

How to make blueberry pie step by step

This traditional recipe combines a perfect pie crust with a juicy blueberry filling. Following these detailed steps and applying the previous tips, you'll achieve a professional and delicious pie.

Step 1: Preparing the pie crust

• In a large bowl, mix 2½ cups of flour with 1 teaspoon of salt, ensuring they are well integrated for even flavor distribution.
• Incorporate 225g of cold butter cut into small cubes, working with fingertips until achieving a sandy texture without overworking.
• Gradually add 4-5 tablespoons of ice water while combining the dough with gentle movements, just until a ball forms that pulls away from the bowl.

Step 2: Resting and filling preparation

• Wrap the dough in plastic wrap and refrigerate for 2 hours while preparing the filling, this time is crucial for the butter to cool again.
• In a saucepan, mix 4 cups of blueberries with 1 cup of sugar, 4 tablespoons of cornstarch, 1 tablespoon of lemon juice, and ¼ teaspoon of cinnamon.
• Cook over medium-low heat, stirring gently until thickened and bubbling, approximately 5-7 minutes, then remove from heat and add 1 teaspoon of vanilla.

Step 3: Assembling the pie

• Divide the chilled dough into two parts (60% for the base and 40% for the top), roll out the larger portion on a floured surface into a circle that extends 3cm beyond the pan size.
• Carefully transfer the dough to the greased pan, gently pressing against the bottom and edges, trim excess leaving a 2cm border.
• Pour the warm blueberry filling into the base, ensuring even distribution.

Step 4: Decoration and baking

• Roll out the remaining dough and cut 2cm wide strips to create a decorative lattice over the filling, pressing the edges to seal.
• Beat 1 egg and brush all visible dough surfaces, then sprinkle 2 tablespoons of granulated sugar on top.
• Bake in preheated oven at 400°F for 15 minutes, then reduce to 350°F and continue baking for 35-40 minutes more until the surface is golden and filling bubbles.

Remember to let the pie cool completely on a rack before unmolding or cutting. Patience in this final step is crucial for the filling to set and the pie to maintain its perfect shape.

Tips for unmolding the pie without breaking

Unmolding is one of the most critical moments in pie preparation, but with the correct techniques, you can achieve a perfect result without breaks or accidents.

Pan preparation

• Use quality non-stick spray over the entire surface of the pan before pouring the dough, ensuring uniform coverage.
• Place a circle of parchment paper at the base of the pan, cutting it to exactly the same size.
• If you don't have non-stick spray, grease the pan with butter and lightly dust with flour.

During cooling

• Let the pie rest in the pan until it's completely cold to prevent deformation.
• Cover the pie with aluminum foil when removing from the oven and let it cool before refrigerating for at least 6 hours.

Unmolding process

• Run a thin spatula or knife around the edges of the pan to gently separate the pie.
• If the pie is very stuck, briefly immerse the base of the pan in hot water for 30 seconds.
• For cold pies, use a cardboard base the exact size of the pan covered with aluminum foil and parchment paper to facilitate plating.

Additional tips

• Preferably use springform pans to facilitate the process.
• If using a non-springform pan, place the pan in a container with cold water for a few minutes before unmolding.
• Never try to unmold a hot pie, as it increases the risk of breaking.

Creative decorations beyond the classic lattice

The decoration of a blueberry pie can be as creative as you wish, going beyond the traditional lattice to create unique and personalized designs.

Full Crust Designs

• Cover the pie completely and create decorative vents using cookie cutters in shapes of hearts, stars, or leaves to allow steam to escape.
• Use cut-out letters in the dough to write personalized messages or the name of the pie on the surface.

Lattice Variations

• Create a multiple lattice by alternating wide and thin strips to add more dimension and texture to the design.
• Combine the lattice with braids interwoven between the plain strips for a more elaborate finish.

Decorative Edges

• Design a wavy edge by pressing the dough with fingers in opposite directions.
• Decorate the edge with small dough leaves, slightly moistening them to help them stick.

Thematic Designs

• For an autumn touch, decorate with dough leaves of different sizes distributed across the surface.
• Create geometric designs by combining different shapes cut from the dough.

Final Touches

• Brush the surface with beaten egg to achieve a golden shiny finish.
• Sprinkle sugar over the decoration before baking to give a crystalline and crispy touch.
