In that food processor, you'll want to toss in your desired nut, be it almonds or hazelnuts.
You could throw those nuts in raw, or you could roast them beforehand at 350°F for 10 minutes. It's totally okay not to roast them, but if you do, it will result in a longer shelf life, and it will make the overall process a little bit easier on you.
But, again, this is totally up to you.
After you've tossed your nuts into the processor, roasted or not, you'll want to chop up these puppies as much as you can with your processor.
Don't be alarmed if the processing portion of this recipe takes upwards of 20 minutes or so. You'll really need to chop them up from every angle, so be sure to scrape the interior and sides of the processor periodically throughout the processing portion of the recipe.
It should be noted that for those looking to mimic a Nutella spread, you'll want to peel your nuts before anything. But it's not entirely necessary to do so, however.
If you leave the skin on, you may enjoy some hidden health properties, but the overall taste could wind up being tremendously bitter. So, again, this is totally your call.
Once that 20 minute time period has elapsed, you can then add in your cannabis-infused cooking oil. You'll want to stir in the same portion as you would with the store-bought route, about 1 dose per serving. Which, again, comes out to about 2 tablespoons of butter and/or spread.
You could leave it as is, but where's the fun in that.
