Pine nuts are small, elongated seeds harvested from pine cones of certain pine tree species. They have a delicate, buttery flavor with a slightly sweet and nutty taste. Pine nuts are commonly used in a variety of culinary dishes, including salads, pesto sauce, and baked goods. They are a good source of healthy fats, protein, and essential nutrients like magnesium and vitamin E. Pine nuts are often toasted to enhance their flavor and can be enjoyed on their own as a snack or as a flavorful addition to many recipes.
