I love pistachios, and it is my favorite nut. Making this eggless ice cream is not as difficult or exotic as one may think. Buy unsalted shelled pistachios, and use a good blender such as a Vitamix (did I ever tell you that I love my Vitamix?). You can substitute pistachios with walnuts (a bit bitter ice cream) or almonds. You can also use pistachio butter instead of pistachios (I would suggest 3/4 cup).
