I also whipped-up a quadruple batch of chocolate mousse. But we all had such a big dinner, no-one could face dessert, so we've brought it back home. What a shame! It's the easiest recipe:
Single quantity (serves 4, but I think they're rather scant serves!):
Melt 4oz chocolate good quality dark chocolate and 2T milk together in a large bowl - you'll eventually put everything into this bowl. Separate 2 eggs and beat the whites until stiff. Add the yolks to the chocolate. Rinse and dry the beaters and in another bowl beat about 1/2c cream until thick. Fold the cream into the chocolate, then fold in the beaten egg whites. Cover and refrigerate for an hour or so to set.
