Rosie’s Divine Amaretto Chocolate Mousse
60g/2 oz amaretto biscuits (approximately 12), crushed
150g/6 oz high-content chocolate (70% or more)
1 tbsp salted butter, or unsalted plus pinch salt
1 tbsp strong espresso coffee
1 tbsp Amaretto liqueuer
4 eggs, separated
1 tbsp white sugar
300 ml/1 1/4 c double/heavy cream
Line a loaf tin with plastic wrap, then scatter half the crushed biscuits on the bottom. Melt the chocolate in a bowl placed over simmering water, then stir in the butter, coffee and Amaretto. Set aside to cool.
Whisk the egg whites with an electric mixer or by hand until stiff. Set aside. Whisk the egg yolks and sugar together until thickened, creamy and about doubled in volume, and set aside. Whip the cream until just whipped.
Fold the egg whites into the chocolate mixture, then the yolk mixture, then the whipped cream. Pour into loaf pan and scatter remaining biscuits on top. Refrigerate for at least 8 hours or overnight. Service in slices with fresh berries, if liked, or whipped cream. A glass of Amaretto on the side would be lovely as well.
