  • Set aside to cool for 10-20 minutes.
  • Second Mixture
  • Pour 20g of the 100g sugar into a non-stick pan on a medium heat and wait for it to dissolve. As it dissolves, add another 20g of sugar. Repeat this process until there’s no more sugar left.
  • Add the toasted hazelnuts to the pan and coat all the hazelnuts with the caramlised sugar.
  • Remove from the pan to another tray straight away to stop it from burning.
  • Set aside to cool.

  • Break the milk biscuits in half and add to the mixture and mix with a wooden spoon.
  • Break the caramelised hazelnuts with your hands and add to a grinder to crush the hazelnuts.
  • Add the crushed hazelnuts to the mixture and combine well.
  • Rolling Process
  • Lay down a sheet of baking paper and scoop the mixture onto the sheet horizontally.
  • Start to roll into a log. Add a sheet of cling wrap to keep the roll the same size from beginning to end.
  • Continue to roll until the log is securely wrapped and tie the ends like a piece of candy.
  • Place in freezer for at least 2 hours.
