In a dry skillet, toast your hazelnuts until fragrant (about 4 – 5 minutes over a medium heat). Place on a clean kitchen towel and allow to cool. Once cool rub towel over them to loosen and remove as much of their skins as possible. Place in a food processor or high-speed blender and process until fine crumbs. Add remaining ingredients and blend until smooth. Taste and adjust salt and stevia if needed.
