Pistachio Nut, Grade Standard : Food Grade for Eating Out OF Hand

Pistachio is the fruit of Pistacchio vera tree. It is a yellow-green coloured nut found inside a hard, naturally beiged colored shell. The shells of some pistachios are colored red (with vegetable dye), while others have been blanched until white.
Pistachios aren’t actually nuts. Pistachio 'nuts' are actually seeds of red or yellow plum-like fruits whose flesh is removed during processing. However, everyone calls them a nut because they look like 'nuts' and belong to the cashew family. Other things in the cashew family include sumac, mangos, and poison ivy.
Pistachio nuts have a delicate, subtle flavor that is wonderful either for eating out of hand or for flavoring both sweet and savory dishes.

In fact, pistachios contain more magnesium and copper than potatoes, milk, or bread.

They are also rich in dietary fibre: in fact, an ounce of nuts contains more fibre than half a cup of spinach.
