1. Prep the Pistachios
First things first: if your pistachios still have their skins, you’ll want to blanch them. The skins can make your cream less smooth and give it a brownish tint, which isn’t as visually appealing.
Here’s how to blanch pistachios:

• Boil a pot of water and toss in the pistachios. Let them cook for 2-3 minutes.
• Drain them and transfer them to a clean kitchen towel. Rub them gently to remove the skins.
• Before moving to the next step let them dry completely.
  I know this next part can be somewhat laborious, but it’s well worth all the effort: blanched pistachios not only look better and more appealing, but they’re also much smoother to blend.

2. Toast the Pistachio:
Toasting pistachios is truly a game-changer. Not only does it intensify their flavor, but it also adds a subtle nuttiness that takes your cream to the next level.
To do this, simply heat a dry skillet over medium heat. Then, toss in the pistachios and stir frequently for about 5 minutes. You’ll know they’re ready when they become fragrant and slightly golden. Once done, be sure to let them cool before blending.

3. Blend the Pistachios
Here’s the fun part! Toss those toasted pistachios into your food processor or high-speed blender and pulse them until you have broken them down into fine crumbs. Once they are crumbly, keep them going and slowly drizzle the oil in.
And imagine it’s patience. It’ll seem so negative and dry and chunky at first, but let this all keep going. The oils in the pistachios will release and transform it all into a smooth paste.

4. Sweeten and Creamify
When the last thing is nothing more than a smooth paste, the next step is to add the powdered sugar, whipped cream, vanilla extract, and salt. At this time, all further processing would occur until smooth and creamy. You might find that scraping down the sides of the blender toward the end is necessary a couple of times.

Pro tip: If the mixture seems too thick, add a splash of cream or milk. If it’s too runny, you can blend in a few more pistachios to thicken it up.

5. Taste and Adjust

That is entirely up to personal taste and preference. If you want it to be a little sweeter, then add just a pinch more powdered sugar. If it is the richness that you are going for, then a little drizzle of oil can also help. Blend again to fine-tune it until it is just perfect.
