Hazelnut and Chocolate Pop Rocks Mousse
For the Pop Rocks candy base
3 oz whole hazelnuts
1 ½ oz milk chocolate
2 tsp ginger spice mix
3 ½ oz pop rocks candy (Strawberry works best)
For the chocolate mousse
12 ½ oz dark chocolate
14 oz heavy cream
Pinch of salt
For the chocolate glaze (ganache)
¾ oz chocolate (same type as for the mousse)
4 oz water
8 whole coffee beans
Couple of pinches of salt
1 oz cocoa powder
2 ½ oz superfine sugar
To make the base, preheat the oven to 350F and roast the hazelnuts for about 10 minutes until lightly golden. Blend to a paste in a food processor, then set aside. Melt the milk chocolate in a bain-marie (a large stainless bowl over a saucepan of simmering shallow water — take care that the water does not touch the bowl) and stir in the ginger spice and pop rocks candy. Next, fold in the hazelnut purée. Place the 3-inch ring molds on a serving dishes and gently press ½ inch of the finished mixture into the base of each mold. Refrigerate for at least 2 hours, or until hardened.
To make the mousse, chop the chocolate into small pieces and place in a metal bowl. Bring 4 oz of the cream to the boil in a small saucepan. Pour it over the chopped chocolate and stir extremely gently until all the chocolate has melted, watching carefully to ensure it doesn’t take on a granular texture. Add the salt to taste. Once the chocolate cream has cooled to room temperature, lightly whip the remaining cream in a mixer to soft peaks, but do not over-whip. Fold into the chocolate mixture. Pour over the base in the ring molds and place in the fridge to set for two hours.
To make the glaze, chop up the chocolate and set aside. Place the water, coffee beans and salt in a saucepan, whisk in the cocoa powder, then set over a medium heat and simmer for about 3 minutes. Meanwhile, put the sugar in a small pan and melt over a medium heat. Superfine sugar will caramelize quickly, so keep an eye on it; when it does, pour over the coffee and cocoa mix — stand back, as it will bubble and spit. Beat in the chopped chocolate and, when melted, pass through a fine sieve (strainer, i.e. a chinois or china cap). When cool, but still liquid, pour over the mousse to your preferred depth and return the finished molds to the fridge to set.
To serve, run a hot knife around the inside of the rings before removing the desserts.
