Break the chocolate up into a bowl and add the butter. Microwave for 30 seconds at a time, stirring in-between, until smooth, melted and glossy. Set aside to cool.
200 grams 70% Dark Chocolate, 30 grams Unsalted butter
Use an electric whisk to whisk the cream to soft, pillowy peaks (3-4 mins). Take care not to over-whisk as the cream will split. Set aside.
250 millilitre Double cream
Separate the egg yolks and whites into two large bowls.
4 medium Eggs
Whisk the egg yolks and caster sugar together for 5 minutes until voluminous and pale yellow (2-3 mins).
2 tablespoons Caster sugar
Whisk the egg whites to stiff peaks (5-6 mins). You should be able to hold the bowl over your head without them falling out! Set this bowl aside for now.
Pour the melted chocolate mixture into the whisked egg yolks and fold to combine.
Add the whipped cream to the same bowl and fold until smooth and combined.
Add the whisked egg whites in two stages, gently folding in a figure-of-eight motion until the chocolate mousse mixture is even and combined. Take care not to overmix, otherwise you'll knock out too much air.
Divide the mousse mixture evenly between two large or four small serving pots. Cover the pots with clingfilm and chill for at least 3 hours or overnight until set.
When ready to serve, dust with cocoa powder and top with a spoonful of whipped cream. Garnish with grated dark chocolate and a fresh raspberry.
