Pistachio

Pistachios are the seeds of the pistachio tree. They’re usually green, and they taste slightly sweet. They’re called nuts, but botanically pistachios are seeds. People have been eating them for thousands of years.

The kernels can be different colors, ranging from yellow to shades of green. They’re usually about an inch long and half an inch in diameter. If you want to taste one, you’ll have to crack open its hard shell first.
