Arrange drained citrus in a casserole dish. Douse fruit with liqueur. Top fruit with 3 handfuls of brown sugar sprinkled evenly over the top. Place casserole under a hot broiler 6 inches from heat source for 7 or 8 minutes until sugar just begins to brown and bubble. Garnish warm casserole with torn or chopped fresh mint leaves and serve.
