Chocolate Mousse
- 200g dark chocolate, chopped
- 3 large eggs, separated
- 75g granulated sugar
- 150ml heavy cream
- 50g unsalted butter
Instructions
- Prepare the chocolate: Melt the dark chocolate and butter together using a double boiler or microwave in short bursts, stirring frequently until smooth and glossy. Set aside to cool slightly.
- Whip egg yolks and sugar: In a bowl, whisk the egg yolks with half the sugar until the mixture becomes pale and creamy.
- Combine chocolate and yolk mixture: Gently fold the melted chocolate into the egg yolk mixture until well combined.
- Whip the egg whites: In a separate clean bowl, beat the egg whites until soft peaks form. Gradually add the remaining sugar and continue whipping until stiff peaks form.
- Whip the cream: In another bowl, whip the heavy cream until it holds soft peaks.
- Fold components together: Carefully fold the whipped cream into the chocolate and yolk mixture, then gently fold in the whipped egg whites to retain airiness.

Notes
- Use high-quality dark chocolate for the best flavor.
- Ensure the melted chocolate is not too hot when mixing with eggs to prevent curdling.
- Be gentle when folding whipped egg whites and cream to maintain mousse lightness.
- Chilling the mousse overnight enhances the texture and flavor melding.
- Eggs are raw or lightly cooked in mousse; use fresh, high-quality eggs or pasteurized eggs for safety.
