Walnüssen

Walnüssen are the seeds of trees belonging to the genus Juglans. The most common species cultivated for their nuts is the Persian walnut, Juglans regia, also known as the common walnut. These nuts are encased in a hard, woody shell, which is typically dehiscent, meaning it splits open when ripe. Inside the shell is the edible kernel, which is divided into two convoluted halves.

Walnuts have been consumed by humans for thousands of years and are believed to have originated in Persia. They are now grown in many temperate regions around the world, with major production areas including China, the United States, Iran, and Turkey. The trees are relatively long-lived and can produce nuts for many decades.

Nutritionally, walnuts are a rich source of healthy fats, particularly omega-3 fatty acids, as well as protein, fiber, vitamins, and minerals. They are a popular ingredient in both sweet and savory dishes, appearing in baked goods, salads, and pestos. Their distinct, slightly bitter flavor also makes them a versatile culinary ingredient. Walnuts are also processed into walnut oil, which is used in cooking and for industrial purposes. The cultivation and harvesting of walnuts are significant agricultural activities in many countries.
