The June Oven’s Fruit Pie Cook-Program gives beginners the confidence to pull off a homemade pie with ready-made pie crust. Even seasoned bakers can rely on this recipe by swapping the pre-made pie crusts with a favorite homemade double-crust pie dough recipe. Feel free to adjust the amount of sugar in the filling depending on the sweetness of the berries. If you use frozen berries, add another 2 tablespoons of flour to the filling.
