Instructions

1. Step 1: Chop 6 oz bittersweet chocolate and melt gently over a double boiler or in 30-second bursts in the microwave, stirring until smooth. Set aside to cool slightly.
2. Step 2: In a chilled mixing bowl, whip 1 cup heavy cream with 2 tbsp granulated sugar, 1/2 tsp vanilla extract, and 1/4 tsp ground cinnamon until soft peaks form.
3. Step 3: In a separate clean bowl, beat 3 large egg whites with 1 pinch salt until stiff peaks form.
