There is one thing we can promise: this soufflé will not fall flat! This twist on the original is a stress-free alternative and served cold, which means it can be made ahead of time. It’s more or less a chocolate mousse that is aerated by an Italian meringue. The chocolate granita topping cuts through the sweetness of the mousse and could be complemented, if you wish, with a touch of sharp passionfruit pulp or a few pomegranate arils. You may choose to place the mousse in the freezer 30 minutes before serving to add some chill to your soufflé.
