Preheat oven to 325. Roll out 1/2 dough until 1/8-in. thick and line six individual tart pans. Peel, core, and thinly slice the apples. Heat 3 tablespoons butter in skillet, saute apples 3-4 minutes until golden. Sprinkle sauteing apple slices with sugar.
Meanwhile, warm Calvados in saucepan. Pour warm brandy over apple slices, cover skillet for a few seconds, uncover, ignite. Fill tart pans with flambeed apple slices. Cut remaining 1-1/2 tablespoons butter in 6 pieces, lay 1 piece on each tart. Drizzle warm Caramel Sauce over tart fillings to glaze. Roll out remaining puff pastry dough until 1/8-in. thick. Cut out tops to cover tart shells. Cut design in center of each top with cookie cutter; place on top of tarts, leaving sides open. Gently brush dough with beaten egg. Bake in preheated oven 30 minute, until golden brown. Serve with Caramel Ice Cream.
