This process involves scolding the hazelnuts in boiling water with bicarbonate of soda (which acts as a catalyst) before soaking in icy cold water to loosen the skins.



  • In a deep pan boil the water and slowly add the bicarbonate of soda.
  • Add the hazelnuts to the water and boil for about 5 minutes.
  • Remove the hazelnuts from the pan using a slotted spoon to drain any excess water and immediately put in a bowl of cold water with the ice.
  • Using your fingers try and remove the skins. If the skins are still tough boil for an extra 2 minutes, otherwise let the hazelnuts soak for a few minutes.
  • After soaking remove from the ice water and place the hazelnuts between two clean tea towels and rub together to easily remove the skins.
  • Store cool and dry in an airtight container for up to 3 months. Chop, grind or toast and add to cakes and bakes.
