Michelle Darmody: How to make a rich and velvety chocolate orange mousse

"You want a nice light fluffy feel when you spoon into the dessert that belies the rich and intense flavour in your mouth."

French artist Henri de Toulouse-Lautrec, who was famous for depicting life in Paris in the late 1800s, is often credited with inventing the chocolate mousse. 

The rich and velvety texture of mousse is part of its appeal. 

How you combine the ingredients, and the amount of air you can add during the process, is important in creating the wonderful airy smoothness.
