I saw a recipe for this combo somewhere and now cannot for the life of me remember where it was. I've searched this board without success. Epicurious has a recipe for blueberry, raspberry, cranberry pie but the one I saw didn't have raspberries.
It's weird because I bought frozen blueberries and fresh cranberries specifically for the pie and now I'm at a loss. Of course I could wing it, but am hoping that somebody remembers seeing such a recipe someplace where I can lay my hands on it.
