Walnuts

Walnuts are mild, tender, oily nuts. They grow in two segments inside a hard shell and are typically light brown with deep ridges patterning the surface. White walnuts (or butternuts) and black walnuts are two North American varieties. Butternuts are richer, while black walnuts have a stronger flavor. Walnuts are sold whole in the shell, shelled as halves or pieces, or pickled.
