Method
  1. PRALINE PASTE:

  3. Put the sugar in a medium saucepan and add 1½ tbsp water. Stir to combine.
  4. Place on the heat and brush down the sides of the pot with a wet pastry brush.
  5. Cook until a deep amber colour. Do not stir.
  6. Turn off the heat and add the hazelnuts. Swirl the pan to coat them in caramel and pour onto the prepared tray.
  7. Spread into an even layer and allow to cool and harden.
  8. Chop the praline into small chunks and blend with the oil in a food processor to make a smooth paste.
  9. BROWNIE BASE:
  10. Preheat the oven to 160 C (325 F) and line the base and sides of a 9 inch round springform tin with baking paper.
  11. Melt butter and chocolate together until smooth and combined.
  12. Lightly whisk sugar, eggs and vanilla and stir into the chocolate mixture.
  13. Fold in the flour and salt.
  14. Pour into the prepared pan and spread out into an even layer.
  15. Bake for 8 - 10 minutes, until the top is set.
  16. Allow the brownie to cool completely.
  17. Once it is cool, remove the brownie base from the tin.
  18. Place the same springform tin (without it's base) on a flat tray lined with baking paper. Line the sides of the tin with acetate.
  19. Fit the brownie back into the tin and freeze.
  20. PRALINE CRUNCH:
  21. Melt both chocolates and praline together over a bain marie until smooth.
  22. Stir in salt and feuilletine.
  23. Spread in a thin layer over the brownie base and freeze until set.
  24. CARAMEL MOUSSE:
  25. Heat the cream, glucose, honey and vanilla in a small pot until melted and combined. Set aside but keep warm.
  26. Make a dry caramel by putting the sugar in a medium pot and heating until it melts. Cook until it is a dark amber colour.
  27. Turn off the heat and pour the warm cream mixture into the caramel, stirring constantly until smooth.
  28. Meanwhile, whisk the egg yolks in a stand mixer until they are thick and pale.
  29. Pour in caramel slowly, while constantly whipping on a high speed.
  30. Soak gelatin in cold water to soften. Squeeze out the excess water and put it in a small metal bowl. Place the small bowl over a larger bowl of hot water, stirring the gelatine until it dissolves into a liquid.
  31. Add it to the caramel mix and stir to combine.
  32. Cool to room temperature.
  33. Fold through the semi whipped cream.
