Wash the currants and remove them from the stems with a fork. Wash, clean and quarter the strawberries. Puree the strawberries and currants with the cutting stick of the hand mixer and pass through a sieve. Mix with crème de cassis, sugar and lemon juice. Peel oranges so that the white skin is completely removed. Cut out the fillets between the parting skins.
Cut out 4 large balls from the ice cream. Spread the berry puree on 4 plates. Put the ice cream scoops in and arrange the orange fillets around them in a star shape. Sprinkle with the pistachios. Dust the edge of the plate with icing sugar
