Follow these step-by-step instructions to whip up a batch of chocolate mousse that will impress your family and friends.

1. Melt the Chocolate Chips
   Begin by melting the chocolate chips in a heatproof bowl over simmering water. Stir the chocolate until it’s completely smooth, then set it aside to cool slightly.
2. Whisk the Eggs and Sugar
   In a separate bowl, whisk together the eggs and sugar until the mixture becomes fluffy. This step is crucial for achieving the mousse’s signature lightness.
3. Combine Chocolate and Egg Mixtures
   Gently mix the melted chocolate into the egg mixture. Be careful to incorporate it smoothly to maintain the airy texture.
4. Whip the Cream
   In another bowl, whip the heavy cream with vanilla extract and a pinch of salt until soft peaks form. This will add a creamy texture to the mousse.
5. Fold the Whipped Cream
   Carefully fold the whipped cream into the chocolate mixture until everything is well combined and smooth. The folding technique helps retain the fluffiness.
6. Chill the Mousse
   Spoon the mousse into individual serving dishes and chill for at least 2 hours. This allows the mousse to set and flavors to meld.
