My Triple Berry Pie is one of my most popular pies. I didn't think I could improve on this pie, but I have by adding dark, sweet cherries to the filling... the result is pure AMAZING! This buttery, flaky crust is filled to the top with blueberries, blackberries, raspberries, and dark, sweet cherries. The top crust is dusted with course sugar and cinnamon. You want this pie at your 4th of July party this year!
