2 Each Pie Crust Recipe
Pour the raspberries into the crust in the pie dish.
Top with the second pie crust and decorate how you like. Place the readied pie into the refrigerator and turn your oven on to 425°F with a rack in the lowest position.
Once the oven is ready remove the pie from the refrigerator and place directly in the oven on that lower rack. Bake for 10 minutes.
Turn the oven down to 350°F and bake for a further 40 minutes.
Remove from the oven and allow to rest for 30 minutes before slicing into the pie.
