What Are Walnuts?

Walnuts are small, round nuts enclosed in a hard, wrinkled shell that must be cracked open to reveal the edible kernel inside. The inner kernel is pale and off-white, with a firm, crunchy texture and a slightly oily surface. When freshly cracked, walnuts emit a pleasant, earthy aroma. Their flavor is mildly sweet and nutty, making them a delicious addition to a wide range of dishes.

Walnuts are available in various forms—in-shell, shelled (whole halves), chopped, or ground walnut meal—depending on the application and market requirements.
