Pine nuts are the edible seeds of pine trees and are commonly used in various culinary dishes around the world. They have a delicate, sweet flavor and a buttery texture, making them a popular ingredient in both savory and sweet recipes.

Pine nuts are often used in Mediterranean cuisine, especially in dishes like pesto sauce, salads, and baked goods. They can also be toasted and sprinkled over dishes to add a crunchy texture and nutty flavor.

These nuts are a good source of nutrients, including protein, healthy fats, vitamins, and minerals like magnesium and zinc. However, they are also high in calories, so it's best to consume them in moderation.

Harvesting pine nuts can be labor-intensive, as they are typically extracted from the pine cones of specific pine tree species. This process involves removing the seeds from the cones and then shelling them to extract the edible kernel inside.

Overall, pine nuts add a unique flavor and texture to many dishes and are a versatile ingredient in the kitchen.
