Blueberry Pie

pie pastry
3 pints of blueberries, cleaned and stems removed
2 Tbsp freshly squeezed lemon juice
1/4 cup all-purpose flour (for thickening)
1/2 cup sugar
1/4 teaspoon ground cinnamon
2 Tbsp unsalted butter, cut into small pieces

Egg wash ingredients:
1 egg
1 Tbsp milk

Prepare crust. On a lightly floured work surface, roll out half of the dough to 1/8-inch-thick circle, about 13 inches in diameter. Drape dough over a 9-inch pie pan and put into the refrigerator to chill for about 30 minutes.

Whisk egg and milk together to make an egg wash and set aside.

Combine blueberries, flour, cinnamon, lemon juice, and sugar and place in the chilled bottom crust of the pie pan. Dot the top with butter pieces. Roll out the remaining dough to the same size and thickness. Brush the rim of the crust with the egg wash, place the other piece of dough on top, trim to 1/2 inch over the edge of the pan, and crimp the edges with a fork or your fingers. Transfer the pie to the refrigerator to chill until firm, about 30 minutes. Heat oven to 425°F.

Remove from refrigerator. Brush the top with egg wash. Score the pie on the top with two perpendicular cuts (so steam can escape while cooking). Bake for 20 minutes at 425°. Reduce heat to 350°F and bake for 30 to 40 minutes more or until juices are bubbling. Let cool before serving.
