Pistachio Nuts (Pistacia vera)
Pistachio nuts (Pistacia vera) are also known as green almonds. The green color varies according to the levels of chlorophyll contained in the nuts.
Pistacia vera is a small tree and is thought to have originated from Persia. The pistachio tree is now found through the Mediterranean, India, Asia and California. They are hardy trees and flourish under high temperatures and low rainfall. The fully-grown pistachio shell opens up during drying, but the immature kernels remain closed.
Pistachios are used to flavor and colour ice cream, Turkish delight, and halva. Ground pistachio paste has traditionally been used as a thickener, too.
The majority of these nuts are bought roasted and salted; however, fresh and raw organic ones are available.
Pistachios are rich in oil, calcium, vitamin A, and they are an excellent source of iron and potassium.
