I’ve heard that pistachios have a rich history, what is it?

Of course, pistachio nuts have a rich and fascinating history. They are one of the oldest flowering nut trees which have been described as being native to Iran[1], Central Asia, and Western Asia. Recent archeological proof in Turkey implies that people were enjoying them as early as 7,000 B.C. Growing in hot environments, pistachios expanded from the Middle East to the Mediterranean, quickly becoming a treasured food between royalty, tourists and common folk alike.

Myth has it that the Queen of Sheba declared pistachios as an exclusively royal food, going so far as to forbid peasants from producing the nut for their personal use. Nebuchadnezzar, the ancient ruler of Babylon, had pistachio trees planted in his famous hanging gardens. Also, in the first century A.D., Emperor Vitellius debuted this expensive nut in Rome. According to Muslim myth, the pistachio nut was one of the fruits which were brought to Earth by Adam.

The pistachio’s high nutritional value and long storage life also made it an indispensable travel item among early explorers and traders. Along with almonds, pistachios were frequently carried by travelers across the ancient Silk Road that connected China with the West.

What does a pistachio tree and fruit look like?

The tree grows up to 10 meters tall. It has deciduous pinnate leaves 10 to 20 centimeters long. They’re dioecious, with separate male and female trees. The flowers are unisexual and apetalous borne in panicles. The seed has a mauve-colored peel and bright green flesh, with a unique flavor. When the fruit ripens, the shell changes from green to an autumnal red/orange and slowly breaks partly open.

Pistachio fruits are known as drupes; each fruit consists of:

  • The exocarp: a red to greenish-yellow outer husk
  • The mesocarp: a fleshy green middle layer
  • The endocarp: a creamy white shell surrounding the nut

Unless you are growing them yourself, the only time you’re likely to see an entire pistachio drupe is right after the harvest. Processing excludes both the outer layers.
