The night before you want to make your milk, soak ½ cup dry, unsalted, shelled pistachio nuts in 3 cups purified water.
The next day, or after soaking for at least 8 hours, squeeze the pistachio meats out of their purply-brown encasings. Discard the casings and set aside the soft, brilliant green nut meats. Once all are free of their casings, rinse once.
Place pistachios in VitaMix or high powered blender with 2 ½ cups purified water. Blend on high until all is completely smooth, about 1-2 minutes.
Pour through a nut milk bag, or other fine straining tool, squeezing to remove every last drop of liquid from the pistachio pulp.
Return the milk to the blender, and add honey, vanilla, cardamom, sea salt, and orange blossom water. Blend to incorporate, about 30 seconds. Taste (perhaps gasp, as I diand adjust flavor as you like.
Drink voraciously by itself, or eat with other creamy things, like ice cream, and bright berries. Let me know how you’re going to use yours in comments below!
