Place the potatoes on a baking sheet and bake until tender, about 1 hour. Remove from the oven and let rest until just cool enough to handle. Lower the oven to 350

While still somewhat hot, peel the potatoes and place in a large bowl. Discard the skins and tough stringy fibers. Add butter and with an electric mixer beat out the lumps. Add sugar, eggs, orange juice, heavy cream, and brandy and mix until smooth. Add the cinnamon, salt, and nutmeg, and mix well. Re-season to taste. Bake about 20 mins until puffed and slightly golden brown.
