I got this recipe from Epicurious.com. I wanted to try making a blueberry pie using frozen blueberries. This one came out very good. It wasn't overly sweet which my DH loved. However, I found it a bit runny. Next time I make it, I will increase the amount of tapioca by one or two tablespoons to thicken it more. You can also use 6 cups of fresh wild blueberries in this. I can't find them here in the south west so I opted to use the frozen. I served this a al mode. I used Vanilla Soy Ice Cream which was really delicious. The pie crust I used with this is: http://www.recipezaar.com/97877 In my opinion, this is one of the best crusts for a berry pie. This recipe is for one crust only so you will have to double it. When I make this crust I prepare each crust separately and put the first one into the fridge to chill while I make the second. Then I assemble the pie.
