This is a pie from my childhood, maybe from yours too! Only we used cherry pie filling for the topping and it was called Cherry O Cream Cheese Pie. I remember Mom making this pie for the holidays, and loving that lemony cream cheese filling with syrupy cherries on top. I froze several packages of raspberries and blackberries over the summer and thought this would be a perfect topping on an old favorite. Everyone loved the mixed berry version and the coloring was bright and glossy red. Makes you hate to slice into it . . . almost!
