most pies although with blueberry and raspberries they have a bit of a bit to them so i would use 1 cup. add about 1 tablespoon of lemon juice. mix.
now, at this point you can add other spices although you don't have to. for my blueberry pies i like to add a 1/2 t of cinnamon (about - add more if you love it), a slight sprinkle of ground ginger and just a touch of vanilla exact. see the photo (click on it to make it bigger if you'd like) to see amounts.
pour into a prepared crust. you want it to be tall and heaping - try to fit all
