Peel and carefully segment the oranges and grapefruit into a bowl. Add the sugar and chopped mint; taste and add more sugar if necessary. Chill. Serve in pretty little bowls or, alternatively, arrange the segments of orange and grapefruit alternately on the plate in a circle; pour a little juice over the fruit. Garnish with a sprig of fresh mint.
