What They Are
Hazelnuts, the fruit of the hazel tree, have a fuzzy outer husk that opens as the nut ripens; the cream- or tan-colored nut within is covered with a reddish brown paper-thin skin and encased in a smooth shell. Also known as filberts, hazelnuts are available shelled or unshelled, with or without their brown skins, chopped or ground. Pressed hazelnuts produce a strong-tasting oil, similar to walnut oil.
How to Remove Skins
Preheat oven to 375 degrees. Place raw (shelled) hazelnuts in a single layer on a rimmed baking sheet; bake until skins crack, 10 minutes. Transfer warm nuts to a clean kitchen towel and roll up. Rub the nuts in the towel between your hands until most skins have come off. If you’re having trouble removing the skins, toast the nuts for a few minutes more until they’re a little darker in color. Alternatively, you can agitate the nuts in a coarse sieve or colander set over a bowl to break off the skins.
