Puree sugar, 125 g blackberries and yoghurt. Dissolve squeezed out gelatine in a small pot. Stir in 3 tablespoons of cream, then stir into the remaining cream. Chill the cream for about 20 minutes until it starts to gel
Whip the cream until stiff and fold into the cream. Chill the cream for at least 4 hours. Spread chocolate in 4 thin circles (12-15 cm Ø) on baking paper. Cut out circles unevenly and line 4 bowls/bowls with it. Put the bowls in a cool place until the chocolate is firm
Carefully remove the chocolate trays from the baking paper and arrange them on plates. Use a large tablespoon of dumplings to cut off the cream and place in the chocolate bowls. Decorate with lemon balm and remaining blackberries
