Pistachio a sudden 50% loss in the Australian pistachio harvest. Several years of severe drought in Iran around 2008 to 2015 caused significant declines in production. In 2016, world production of pistachios was 1.1 million tonnes, with the United States and Iran as leading producers, together accounting for 68% of the total (table). Secondary producers were Turkey and China. The kernels are often eaten whole, either fresh or roasted and salted, and are also used in pistachio ice cream, kulfi, spumoni, historically in Neapolitan ice cream, pistachio butter, pistachio paste and confections such as baklava, pistachio chocolate, pistachio halva, pistachio lokum
Pistachio Greek "pistakion", from Persian "pesteh". Archaeology shows that pistachio seeds were a common food as early as 6750 BC. Pliny the Elder writes in his "Natural History" that "pistacia", "well known among us", was one of the trees unique to Syria, and that the seed was introduced into Italy by the Roman Proconsul in Syria, Lucius Vitellius the Elder (in office in 35 AD) and into Hispania at the same time by Flaccus Pompeius. The early sixth-century manuscript "De observatione ciborum" ("On the observance of foods") by Anthimus implies that "pistacia" remained well known in Europe in Late Antiquity. Archaeologists
