Pine nut

Pine nuts are the edible seeds of pines (family Pinaceae, genus Pinus). About 20 species of pine produce seeds large enough to be worth harvesting. Other pines have edible seeds too small to be useful as a human food.

Pine nuts have been eaten in Europe and Asia since the Paleolithic period. They are often added to meat, fish, salads and vegetable dishes or baked into bread. In Italian they are called pinoli. They are an essential part of Italian pesto sauce.

Pine nuts can be pressed to extract pine nut oil, which is valued for its mild, nutty flavour. The large edible seeds of the Southern Hemisphere conifer genus Araucaria produce nuts rather like pine nuts.
