A charlotte is any dessert that's moulded into a container lined with sponge fingers or boudoir biscuits (purchased at a bakery or supermarket). It’s normally easy to prepare; hardly takes 15 min.
Make the syrup by mixing equal amount of sugar and water flavour it with adding same amount of rum or brandy to taste.
First line the bottom as well as sides of a container with clean wrap & then with sponge fingers soaked in sugary alcoholic syrup. Now layer it alternatively with chocolate mousse and sponge fingers in a way that top layer should be covered with sponge fingers. Then cover with clean wrap tightly and lid. Leave it to chill for more then 12 hours.
To serve, invert dish onto serving plate and unmold charlotte. Carefully remove plastic wrap. (Variation can be done using vanilla mousse & chocolate mousse alternatively). While serving dust with icing sugar and decorate with fruits or with cold custard or whipped cream.
