Ingredients

Instructions

  1. Step 1: Chop 6 oz dark chocolate finely and melt gently in a double boiler or microwave, stirring until smooth; set aside to cool slightly.
  2. Step 2: Whip 1 cup heavy cream in a chilled bowl using an electric mixer until soft peaks form; refrigerate.
  3. Step 3: In a separate clean bowl, beat 3 large egg whites with a pinch of salt until foamy, then gradually add 1/4 cup granulated sugar and continue beating until stiff, glossy peaks form.
  4. Step 4: Fold the melted chocolate gently into the whipped cream until combined, then carefully fold the egg whites into the chocolate-cream mixture in three additions, preserving the airy texture.
  5. Step 5: To make the hazelnut praline, toast 1/2 cup hazelnuts in a dry skillet over medium heat for 5 minutes until fragrant and golden; chop roughly.
  6. Step 6: In a small saucepan, combine 1/4 cup granulated sugar and 2 tbsp water, cook over medium heat without stirring until it turns a deep amber caramel color; quickly stir in the toasted hazelnuts, pour onto parchment paper, and let cool before breaking into small pieces.
  7. Step 7: Spoon the mousse into serving glasses, sprinkle each with hazelnut praline pieces, and chill for at least 2 hours before serving.
