Since we are buried in berries, (and on our way to pick up more) I have learned to make a proper berry pie. The first time I used blueberries. This time I used blackberries. Here is my recipe.
two pints blackberries
juice of one lemon
zest of one lemon
pinch of nutmeg
4 tbsp cornstarch
1/2 cup sugar
Mix all ingredients in a bowl and mash a bit with a fork.
I like to use this pre-made pie crust to save time. The box comes with two crusts, use the larger one for the bottom. Lightly grease the pie pan. Roll out the larger crust and press into pan. Fill with berry mixture. Roll out the other crust and use wet hands to moisten the pie facing side of it. Use fingers to join the crusts and crimp around the edge. Cut slits in middle of pie.
Bake at 375 for an hour and a half. Place foil over the edge of the pie around the 30 minute mark if it is browning too quickly. Place foil over the whole pie around the 1 hour mark if it is properly browned. Remove from oven and let the pie set for two hours.
It is best served warm with ice cream.
