Steps
1. Chop the dark chocolate finely and set aside.
2. In a small saucepan, heat half of the cream with cinnamon, nutmeg, and a pinch of salt until just simmering; remove from heat.
3. Pour the hot spiced cream over the chopped chocolate and let it sit for 2 minutes.
4. Stir gently until the chocolate is fully melted and the mixture is smooth.
5. In a separate bowl, whip the remaining cream with sugar and vanilla extract until soft peaks form.
6. Fold the whipped cream gently into the chocolate mixture until fully combined.
7. Spoon the mousse into a serving glass and refrigerate for at least 2 hours.
8. Before serving, garnish with fresh raspberries and mint leaves.
