Pistachios grow well under hot, dry climates with cool winters. They are currently being cultivated in large scale in the orchards in the USA, Iran, Syria, Turkey, and China. After plantation, the plant takes approximately eight to ten years until it produces its first major crop. Once established, it keeps bearing fruits for centuries.

The fruit, in fact, is a drupe (a fruit with large central single seed) and the seed kernel is actually the edible portion. They are borne in heavy clusters somewhat like that of grapes bunch. Exteriorly, the mature fruit features off white colored, hard, shell with splits apart exposing yellow-light green colored oblong kernel, which measures about 1 inch in length and 1/2 inch in diameter.

Selection and storage

Pistachio-nuts

Pistachios are available in the markets year around. In the grocery store, different forms of nuts are available such as shelled, unshelled, salted, sweetened etc. Try to buy whole “unshelled” or “with shell” nuts instead of processed ones. They are generally available in the airtight packs as well as in bulk bins.

Whole nuts should feature healthy looking, off white color shell, have compact and uniform in size, and feel heavy in hand. They should be free from cracks other than the natural split, mold, spots, and free of rancid smell.

Unshelled pistachios can be placed in cool dry place for many months, while shelled (without the shell) kernels should be placed inside airtight container and kept in the refrigerator to avoid them turn rancid.

• Roasted and crushed nuts often sprinkled over salads, desserts, particularly sundaes and other icecream based preparations, biscuits, sweets and cakes.
