Peel the hazelnuts while they are still hot, and transfer them into a food processor or blender. Go ahead and pulse the nuts for 5 minutes or so until they become creamy. Scrape down the sides during the process so there aren’t any chunks of hazelnuts left behind.

Add the rest of the ingredients to the blender and pulse again, ensuring everything is well-combined and smooth. The goal is for no small bits of hazelnuts to be left behind as they ruin the overall texture, as it’s supposed to be thick and silky smooth.
