Berry Pie

On Saturday morning I went to the farmers market and bought 3 pints of black berries.   By the time I opened the bag that evening they were beginning to be moldy.  But I'd already made my crust and needed a filling.  So, last night I went to the grocery store and bought frozen black berries.  Today I made the pie.  Here is my recipe.

Ingredients
2 pints black berries (fresh or frozen)
3/4 cup granulated white sugar
1/2 cup all purpose flour
1 bottom pie crust (I use a basic 321 pastry recipe with a little sugar added)
1 top pie crust
2 tablespoons milk
Juice of 1/4 lemon

Directions
Pre-heat oven to 425
Mix 1/2 cup sugar with 1/2 cup flour and 3 1/2 cups of berries.  This is the filing.  Put the filling in the bottom pie crust.  Add the remainder of the berries.  Sprinkle with lemon juice.  Put top crust on and pinch closed around the edge. Cut some vents in the top crust to let the steam out.  Brush the top with milk.  Sprinkle with sugar.  Bake in the 425 F oven for 15 minutes then reduce heat to 375 F and bake until the filling bubbles and the top crust is light brown, about 20 minutes.  Cool on wire rack before eating.
