Pine nuts are small, soft seeds harvested from certain pine cones, prized for their rich, buttery flavor and delicate, slightly crunchy texture. They are commonly used in Mediterranean cuisine, notably in pesto, salads, and pasta dishes, and are also a key ingredient in Middle Eastern recipes like kashk-e bademjan. Historically, pine nuts have been valued since ancient times, often considered a luxury ingredient due to their labor-intensive harvesting process. Their unique nutty taste adds depth and richness to a variety of culinary creations across different cultures.
