Chop the chocolate and melt it over a warm water bath. Let it cool down a little. Whip 600 g cream until stiff. Stir about 1/4 of the cream into the chocolate. Then carefully fold everything with 3 tbsp. sugar into the remaining cream. Spread the cream on the base until smooth. Place in a cool place for about 30 minutes.
