Peel and cut bananas in half lengthwise. Sprinkle with sugar, enough to lightly coat the bananas. Broil in oven until the sugar caramelizes. In saucepan, combine sugar with a little bit of water just enough to dissolve sugar, (very little) and place on stove till it becomes a syrup. Just before taking it off the stove, add the currants. When the bananas come out of the oven, top with currant mixture and serve hot.
