What is Walnut?
Walnuts are edible seeds from trees of the genus Juglans, particularly the Persian or English walnut, Juglans regia. They are encased in a hard shell, typically harvested in the fall, and are known for their distinctive lobed appearance resembling a brain. Walnuts are prized for their high nutritional value, offering a good source of omega-3 fatty acids, antioxidants, and essential vitamins and minerals. They are commonly consumed raw, roasted, or as an ingredient in dishes like salads, desserts, and baked goods.
