This is the specialty of the Dufour family at the Ferme Auberge de la Recette farm/inn in France, in the heart of brie country. We ate there one day because we'd read such good things about their brie pie. I didn't ask for the recipe because I didn't think they'd be willing to give it to me. But recently, we learned that the farm was featured on a cooking show, and they explained how to make their famous brie pie! If you are unable to find the different types of brie, using only one type will probably work, although the taste might be a little different. Prep time does not include refrigeration time.
