When consumed fresh from the tree, walnuts have a softer texture and a creamy, slightly bitter flavor. At this stage, they typically have a 20- to 25-percent moisture level. After the walnuts are cleaned and the leathery outer husk is removed, one of the first processing steps these walnuts will undergo is a mechanical drying process. Even those walnuts sold in shell will be dried to achieve an 8-percent moisture level, which results in a snappier and nuttier nut familiar to consumers' palates and also protects the nuts from rot.
