In a shallow gratin baking dish or cast-iron skillet; alternately arrange the grapefruit and orange slices. Sprinkle with brown sugar and dot with butter. Broil the fruit until it is hot and lightly browned; about 5 minutes. Sprinkle with coconut and broil just until the coconut is toasted. Serve immediately. |
