Peel and cut enough potatoes, a combination of baking and waxy potatoes is fine, and place them in a large pot with water to just cover the potatoes. Bring to a boil, cover and cook for 15 minutes. Check the potatoes to see if they are done, and if not you must boil them for another 5 minutes or so.
Remove from the heat, and mash them with a potato masher, while adding sea salt, freshly ground pepper, unsalted butter and chopped up brie cheese (rinds and all.) Add about 1 Tablespoon of butter per serving, and add about 1/10 as much brie cheese as you have potatoes. Adjust the seasoning, and serve.
