Prepare the pie crust dough, wrap tightly, and chill for 30 minutes. Divide into two equal portions after chilling.
02 -
On a floured surface, roll out one portion of dough into a 30 cm diameter circle. Transfer carefully into a 23 cm pie plate without stretching. Set aside.
03 -
Preheat the oven to 190°C (375°F).
04 -
In a large bowl, combine blueberries, sugar, cornstarch, salt, cinnamon, lemon zest, and lemon juice. Toss gently to coat evenly.
05 -
Pour the blueberry filling into the prepared bottom crust.
06 -
Roll out the remaining dough portion into a 30 cm circle on a lightly floured surface.
07 -
Cut the top crust into 1.3 to 2.5 cm wide strips using a knife or pastry wheel.
08 -
Lay strips vertically over the filling, spacing evenly. Weave shorter horizontal strips alternately over and under the vertical strips to form a lattice. Trim excess dough and seal edges by pressing firmly.
09 -
Brush the lattice with egg wash (egg beaten with milk) and sprinkle sparkling sugar if desired.

Place the pie on a baking sheet. Bake for 45–60 minutes until the filling bubbles and crust is golden. Cover edges with foil or a crust shield if browning too quickly.

Remove from oven and cool at room temperature for at least 2 hours to allow filling to set before slicing.
