Step 1

In a large bowl, melt the chocolate in the microwave or using a bain-marie. Allow to cool.

Step 2

Whisk the egg whites using an electric mixer until they reach stiff peaks.

Step 3

Take one-third of the egg white and mix thoroughly into the melted chocolate, to lighten it. Add the remaining egg whites and carefully fold in. Pour into individual pots and chill for at least an hour or overnight in the fridge. Dust with cocoa powder and top with grated chocolate before serving, if liked.
