Dark Orange Choc Mousse

This recipe originally states it serves 4, I happen to disagree, after splitting it into 4 you would go into a sugar coma. A better estimate would be 8-10 servings (I'm assuming its being served after a meal).

300g dark chocolate
30g butter
2 eggs, separated
30ml sugar
45ml orange liqueur (or Van der Hum or Grand Marnier)
250ml cream

• Break up the slab of chocolate and melt it in the liqueur in a bowl over hot water
• Add butter in small blocks, stirring until it has melted
• Beat the sugar and egg yolks until pale and light. Reserve egg whites
• Beat in the melted chocolate and butter, then leave to cool
• Whip the egg whites to stiff peak stage. Be careful not to overbeat
• Whip the cream until stiff
• Fold the egg whites and cream into the chocolate mixture
• Pour into an attractive bowl and chill for several hours before serving

Garnish with crystalised orange / candied orange peel / orange segments. For the super indulgent, drizzle with orange liqueur (or ginger/orange liqueur mix)
