For 4 good portions you will need,
200g good quality dark chocolate. At least 70% cocoa solids
6 medium sized eggs
2 tbsp strong black coffee and 1 tbsp cognac,( optional.)
2 tbsp caster sugar
1 tbsp cocoa powder
Prepare a double boiler by placing a small amount of water in a saucepan and placing a heat proof bowl over the simmering water.
Break the chocolate into pieces and melt in the bowl stirring occasionally. Remove from the heat and allow to cool for 10 min. Separate the eggs and beat the yolks with the coffee or cognac, then beat in the chocolate.
Now whisk the egg whites until firm and peaky, then slowly add the sugar and beat until glossy. Add a large spoonful to the chocolate mixture, mixing well. Then bit by bit add the remaining chocolate mixing all the time until .
Pour into four serving dishes, cover and chill for a couple of hours to set.
This is an extremely rich dessert but for extra indulgence when serving why not whip up some double cream and place on top of the mousse with a sprinkle of cocoa powder to finish off the effect.
