Preheat the oven to 350°F and have a sheet pan ready.
Add the 16 ounce Raw Shelled Pistachios on a sheet pan and, using your hands or a spatula, spread them in an even layer on the sheet pan.
Bake for 5-6 minutes just until fragrant. Allow them to cool for 2-3 minutes.
Transfer the pistachios to a high-powered food processor, add the 1/2 teaspoon Salt, and process for a couple of minutes.
Using a spatula, scrape down the sides and process again for another 2-3 minutes.
Repeat this process until you get a smooth consistency and butter-like texture. This will take an additional 4-5 times of processing and a total of 20 minutes or so, depending on the food processor. Be patient, it will happen. (see note)
Pour the pistachio butter into 2 small jars or one large Jar. It will yield 1.5 cups of pistachio butter. (see note).

Notes
This recipe yields just about 1.5 cups of pistachio butter.
Each serving is 2 tablespoons.
This takes time and patience. Most would add a bit of oil to speed up the process, and the pistachio butter will form quickly and take less time. I didn't think it was necessary to add oil. Pistachios are already high in calories and have their natural Oils. Adding oil is not needed.
The taste is not sweet! If you are looking for a bit of sweetness, I suggest you add about 1/4 cup of honey.
The pistachios do not need to be toasted fully.
If you are going to use already roasted pistachios, try to use light salt or unsalted. I would also recommend peeling the dark skin off if you can. It is a tedious process, but you can boil the pistachios for about 3 minutes. It will help the peeling process. You can also keep the skin on, the pistachio butter will just be a bit darker.
