A pine nut is the edible seed of certain species of pine trees, particularly from the genus Pinus. These small, oval-shaped seeds are often found inside the pine cones and are harvested for their rich, buttery flavor and nutritional benefits. Pine nuts are a good source of protein, healthy fats, vitamins, and minerals, making them a popular ingredient in various dishes, including salads, pesto, and baked goods. Pine nuts are commonly used in Mediterranean cuisine and are a key ingredient in the traditional sauce known as pesto. They can be eaten raw or roasted, enhancing their flavor and texture. Due to their high oil content, pine nuts should be stored in a cool, dry place to prevent them from going rancid.
