Remove the nuts from their shells if not done already.
Preheat the oven to 180C || 350 F and roast the nuts on a baking tray for 10 - 15 minutes until golden. Remove from the oven and allow to cool slightly,
Place in a clean tea towel and rub to remove some of the skins.
Place the hazelnuts in a jar and cover with water and allow to soak an hour or two, or overnight.
Strain and rinse, and then add to a high-powered blender with 2 cups fresh water. Blend until smooth and creamy, around a minute.
Strain through a nut bag or cheesecloth until most of the liquid is removed.
Store in a jar in the fridge up to five days.
