This was a very good pie. I admit I did not use the crust recipe, as I had a couple of refrigerated ones that needed used in addition to the frozen berries. I used a 16 oz bag of berries and approx. half of one more bag that I had leftover. I gave the mixture an extra squirt of lemon juice, about a 1/4 cup more sugar. While the filling was quite tasty, it did not fill the 9" pie plate I used. I needed about a half inch more filling. I'd make this again, but doubling the recipe to fill my pie plate.
