Cut the baking paper into wide strips and wrap them tightly around the paper cups (alternatively cups or small soufflé cups) so that the paper protrudes about 3 cm beyond the rim of the cup. Secure with paperclips.
Sort the raspberries, wash and drain if necessary. Puree 200 g raspberries, 2 tablespoons sugar and vanilla sugar and pass through a fine sieve. Whip the cream until very stiff. Carefully stir in the raspberry puree.
Beat the egg whites until stiff, adding 50 g sugar at the end. Fold into the raspberry cream.
Pour raspberry mixture into the paper cups and smooth the surface. Cover and freeze for at least 6 hours.
Remove the baking paper before serving. Decorate the ice cream with the remaining raspberries.
