Roast 2 cups raw hazelnuts in a 350F oven for 10-15 minutes, or until golden and fragrant. Let cool for a bit, then add to the center of a kitchen towel, gather it up to seal, and rub the nuts around to get most of the skins off. Add the nuts to a food processor or high-speed blender and blend into a thick paste/nut butter. If your nuts are freshly roasted and cooled, you should get a nice creamy nut butter. If it’s not reaching that nut butter consistency, a more coarse paste will work just fine.
