Chocolate mousse with cocoa nib brittle

1.Whisk cream until soft peaks form (1-2 minutes) and set aside. Melt chocolate in a bowl placed over a saucepan of simmering water, stirring occasionally until smooth and glossy, then set aside. Whisk yolks in an electric mixer on high speed until pale (1 minute). Meanwhile, combine Frangelico, vanilla extract and 30ml boiling water in a bowl. While whisking, gradually add to yolks, then whisk until pale and fluffy (1-2 minutes). Reduce speed to low, add melted chocolate and whisk to just combine, then fold in cream. Whisk eggwhite and sugar in the clean bowl of an electric mixer until soft peaks form (1-2 minutes), fold into chocolate mixture and divide among four 350ml serving glasses. Smooth tops and refrigerate to set (3-4 hours).

2.For cocoa nib brittle, stir sugar and 40ml water in a small saucepan over medium-high heat until sugar dissolves, stir in glucose and bring to the boil. Cook until mixture reaches 115C on a sugar thermometer, then add cocoa nibs and stir continuously until mixture reaches 155C. Remove from heat, carefully stir in butter, vanilla and ¼ tsp sea salt (be careful; hot mixture will spit). Add bicarbonate of soda, stir to incorporate, pour onto a sheet of baking paper, top with another sheet of baking paper and roll out thinly with a rolling pin. Set aside to cool completely, then break into shards. Cocoa nib brittle will keep stored in an airtight container for 5 days.
