Sweet Apple Acres apples have always been the best in all of Equestria, but no one had ever been able to figure out what makes them so great. The Apple family insists it's quality control, TLC, and the hardest working ponies in all of Equestria. Of course, this wouldn't be a very good fanfic if that was all there was to it, so read to find out what the real secret is.
