When I had my restaurant in Florida, we made our own desserts. (And everything else, including real mashed potatoes, lumps and all)
One day I was preparing apple pies and cherry pies. When I was finished, I had enough filling left for half of a cherry pie and half of an apple pie. Not being someone that wastes anything (including fabric crumbs) I thought I would combine the two fruits into a pie. Making a long story short, it was so popular, I had to begin making it one of my regular pies. It gives it a very different taste.
