Pour desired amount of hazelnuts out onto the rimmed sheet pan. I entered 8 ounces into the recipe card in order to get the nutritional information, but truly you can use as much as needed.Spread them out evenly and pop the pan into your preheated oven and roast for 4 minutes.
After the first 4 minutes, you can see the skin starting to crackle and peel.
Toss them around and pop them back into the oven for another 4 more minutes.
Repeat this stem 2 to 3 more times until the nuts are fragrant.
Pour the nuts in the center of your clean kitchen towel.
Gather the ends of the towel and twist them together. Shake them with some good effort. The hazelnuts rub against each other, removing their own skin.
Handpick the nuts out of the towel, discarding the skin unless you have a reason to use it.
Use or store in an airtight container. If stored in the pantry these will last for up to 6 months. Store in the refrigerator (1 year) or freezer (up to 2 years).
