For the English-speaking crowd:

From Wikipedia:

Pine nuts are the edible seeds of pine trees (family Pinaceae, genus Pinus). About 20 species of pine produce seeds large enough to be worth harvesting; in other pines the seeds are also edible, but are too small to be of value as a human food.

In Europe, pine nuts come from the Stone Pine (Pinus pinea), which has been cultivated for the nuts for over 6,000 years, and harvested from wild trees for far longer. The Swiss Pine (Pinus cembra) is also used to a very small extent.

In Asia, two species are widely harvested, Korean Pine (Pinus koraiensis) in northeast Asia and Chilgoza Pine (Pinus gerardiana) in the western Himalaya. Four other species, Siberian Pine (Pinus sibirica), Siberian Dwarf Pine (Pinus pumila), Chinese White Pine (Pinus armandii) and Lacebark Pine (Pinus bungeana) are also used to a lesser extent.

Anyway, enough jokes. Here at 72pines, a pine nut is what you need to register. You can only get it from any of our memebers. If you don’t know anyone, please email webmaster (at) 72pines.com for a request or use the pinenut request form on our front page. We will randomly select some emails and send out pine nuts. So keep your fingers crossed.
