How to Make It

Mix flour and 1/2 C measure of sugar together in a large bowl, and add 3 1/2 cups of the berries and stir gently to coat.
Place bottom crust in pie plate, and spoon berry mixture into crust. Then sprinkle remaining 1/2 cup of berries on top. Cover with remaining crust. Seal and crimp crust edges, then brush with the milk and sprinkle with the 1/4 cup measure of sugar. Bake 15 minutes.
Reduce oven temp. to 375 degrees. Bake another 20-25 minutes.
