Start by making your pistachio milk if it is not already prepared. Place all of the pistachio milk ingredients in a high powered blender, and blend until smooth and creamy. Use a nut milk bag or mesh strainer to strain the pistachio milk and store in an airtight container in the fridge.
If you are making a hot beverage, heat your pistachio milk on the stove over medium heat, or in the microwave to desired temp.
Place all of the pistachio matcha milk ingredients in a high powered blender, and blend until smooth and creamy. The blender will create a little froth on the top! Enjoy!
