Walnuts are edible, single-seed stone fruits of the walnut tree, typically sold either in their hard, protective shell or as shelled nutmeats. They are easily recognizable by their wrinkly, brain-like shape and are prized for their rich, slightly earthy, and subtly bitter flavor. Walnuts are classified as one of the healthiest nuts due to their exceptional nutritional profile.
