Pine nuts are small, elongated ivory-colored seeds measuring about 1/2 inch long. When raw, the seeds have a soft texture and a sweet, buttery flavor. They are often lightly toasted to bring out the flavor and to add a little crunch.
Pine nuts are eaten by many cultures around the world and are known by many names. In the U.S., the most popular use is in pesto or as a crunchy salad topper. They are also good for use in desserts like shortbread cookies and for adding a twist to hummus.
