Heat the cream in a saucepan. Break chocolate into pieces and chop. Add the chocolate, except for 5 tbsp., to the cream and melt while stirring. Put the chocolate cream in a mixing bowl and chill for about 3 hours. For the sauce, peel the mango pulp and cut into fine cubes. Wash and clean the chillies, cut them in half lengthwise, remove the seeds and cut the flesh into very fine cubes.
Finely purée lime juice, sugar and half the mango. Stir in chilli and remaining mango cubes. Whip cold chocolate cream with the whisk of the hand mixer until stiff. Carefully fold the rest of the chocolate into the cream, except for a little bit for sprinkling. Arrange cream and sauce in bowls. Sprinkle with remaining chocolate
