Follow the instructions on the link for the Perfect Pie Pastry recipe.
Using a clean surface, dust with flour, and roll out one disc of dough, and the place in a 9 inch pie plate.
Preheat oven to 400°F.
In a large bowl, add blueberries, sugar, starch, lemon zest, cinnamon, nutmeg and salt, combine with a rubber spatula to avoid breaking any berries. Pour the berry mixture into pie plate, drizzle lemon juice, and add dollops of butter.
Roll out second layer of pie dough. Options for the topping are a lattice, or simply lay over the blueberries. Brush the top and sides with beaten egg. Cut slits for the steam to escape if not creating a lattice topping.
Bake for 35-40 minutes or until golden in colour.
Enjoy with ice cream or whipping cream.
