Method
1) Whisk egg yolks at high speed till fluffy and almost double in volume.
2) Melt chocolate using waterbath (Bain Marie) by placing chocolate in a mixing bowl on top of hot water. (Make sure water is not boiling as the high heat will make chocolate lumpy)
3) Add melted chocolate and rum into the beaten egg yolk and mix immediately.
4) In a separate bowl, whisk the Whipping Cream till stiff and fold whipped cream into the chocolate.
5) Pour hot water into gelatine powder to melt it and fold it into the chocolate mousse.
6) Pour chocolate mousse into dessert glass and allow to set in chiller overnight.
7) Melt ganache and spread over the chocolate mousse before decorating with whipped cream on top and serve.
