Preparation

Get these tasks done before you start cooking.

Preparing the Chocolate Mousse

1
Melt chocolate
Melt the dark chocolate in a heatproof bowl over a pan of simmering water. Stir until smooth, then set aside to cool slightly.
Tip: Use high-quality dark chocolate for the best flavor and texture.
2
Whisk yolks
In a separate bowl, whisk the egg yolks and sugar until pale and creamy.
3
Combine chocolate and yolks
Gently fold the melted chocolate into the egg yolk mixture until well combined.

Whipping the Cream

1
Whip heavy cream
In a clean bowl, whisk the heavy cream to soft peaks and fold it into the chocolate mixture.
2
Whisk egg whites
In another bowl, whisk the egg whites and salt to stiff peaks, then gently fold into the chocolate mixture until just combined.
Tip: Ensure all bowls are grease-free when whipping egg whites to achieve the perfect peaks. Use a metal spoon for folding to keep the airiness in the mousse.
3
Chill mousse
Spoon the mousse into individual serving glasses and chill for at least 2 hours.
