Pine nuts, also known as pine seeds or pine kernels, are the edible seeds of pine trees, typically harvested from specific species like the European pine, sugar pine, or the stone pine. They are small, elongated, and have a soft, ivory to light tan color. Pine nuts are prized for their rich, buttery flavor and delicate texture, which make them a popular ingredient in a variety of dishes, particularly in Mediterranean and Italian cuisine. They are commonly used in pesto, salads, baked goods, and as a topping for roasted vegetables or meats.
