Walnuts

Walnut trees are native to eastern North America but are now commonly grown in China, Iran, and within the United States in California and Arizona.

Beneath the husk of the walnut fruit is a wrinkly, globe-shaped nut. The walnut is split into two flat segments to be sold commercially.

Walnuts are available both raw or roasted, and salted or unsalted.
