200 g dark eating chocolate, chopped coarsely
30 g unsalted butter
3 eggs separated
300m l thickened cream whipped
1 Melt chocolate in medium heat proof bowl over medium saucepan of simmering water. Remove from heat; add butter, stir until smooth. Stir in egg yolks. Transfer mixture to large bowl, cover; cool.
2 Beat egg whites in small bowl with electric mixer until soft peaks form. Fold egg whites and cream into chocolate mixture, in two batches.
3 Divide mousse among serving dishes; refrigerate 3 hours or overnight. Serve with extra whipped cream, chocolate curls and fresh raspberries, if desired.
HOW TO KEEP: Store mousse, covered, in refrigerator for up to 2 days. [KP: it compacts overnight and it more "solid/heavy" and not so fluffy, so best eaten on the day.]
