Fraughan Pie (Irish Blueberry Pie)

This recipe comes from “The Ballykissangel Cookbook”,which was leant to me by my friend Joan. Fraughan is the old Irish name for wild bilberries or blueberries. According to the cookbook, the first Sunday in August was the traditional day for picking fraughans. These days, your nearest supermarket is probably a more convenient place to find the main ingredient! And if you read bayou-mimi's review you'll see that you can also makethe filling with frozen blueberries. I haven't made this pie as written, but having read bayou-mimi's review I just had to try the filling! I too used frozen and also followed her excellent suggestion to add some cornstarch, which worked very well indeed. I’m posting the quantities as written in the book, but I suspect that the filling might be a bit tart for some, so I’ve written a taste test into the directions to check the sweetness. I also doubt if I'd be clever enough to to roll out the specified amount of pastry into such large circles (although no doubt the point is to achieve a super-thin crust), so I used another recipe for my pie crust. However Joan says she follows the recipe exactly and it's one of her favorites.
