Briefly blanch the apricots with boiling water and remove the skin. Halve the apricots, stone them and cut them into small cubes. Wash the lemon. Squeeze one half, cut the other half into thin slices.
Peel the banana, cut it into slices and immediately sprinkle it with the lemon juice so that it does not discolour. Sort the raspberries. Place the fruits in a wide glass jug and pour the currant juice over them.
Stir gently. Cover and leave to stand for about 20 minutes. Top up with chilled ginger ale. Garnish with lemon balm if desired. Serve with drinking straws. Keep small spoons ready for the fruit.
