During the summer I am always craving pies, and this one in particular is so versatile and so delicious. You can use any berry you have on hand, I had raspberries, although my favorite is still blackberries. It has a nice custard filling which helps if the berries are a little tart, and the crust's flakiness compliments the creaminess of the filling really well.
I will be making this pie again soon, once our blackberries ripen. That is, if the birds haven't eaten them all!
