Place the dark chocolate and a tiny pinch of salt in a heatproof bowl and sit it over a pan of gently simmering water, making sure the water doesn’t touch the base of the bowl. Leave to slowly melt, stirring occasionally.
Meanwhile, separate your eggs so you have the whites in one bowl and the yolks in another. Add the sugar to the bowl of yolks and beat until the sugar has dissolved and its silky and smooth. Whisk the whites with a pinch of salt until they form soft peaks, beat the cream until slightly thick and just whipped.
Once the chocolate has melted, carefully lift the bowl out of the pan. Add 75ml (3 shots) of amaretto and the cocoa powder to your bowl of yolks and mix well. Add the cream and mix again, then fold through the melted chocolate until it’s well combined. Finish by folding in the egg whites, then keep folding, from the outside in in a figure-of-eight until the mix is smooth and evenly coloured. Spoon or ladle the mousse into a big serving bowl or divide between little glasses or cappuccino cups and put in the fridge for an hour or two until set.
Just before you’re ready to serve, crack few amaretti cookies and serve on the top. You can also use strawberries, any berries, whipped cream and mint to garnish.
