*I've taken the time to roast the hazelnuts, cool them, and then shake them in a plastic container to the remove the skins. I've also made this recipe using raw hazelnuts leaving the skins on. Having experimented with both ways, I now skip the roasting step and just throw the hazelnuts in the blender raw with the skins on. My blender is strong enough to handle the skins and smooth out the hazelnut spread. The roasting does add a depth of flavor, but I think the spread is still great without this step!
