The Hawaiian Macadamia - considered the world's richest, most elegant nut. Macadamia trees grow best in the fertile volcanic soil in Hawaii. The trees take years to mature and the harvest is relatively small. The supply of trees is small, only 35,000 acres are harvested during each nine month growing season. Sweet, buttery macadamias from Hawaii truly are elegant. Expertly roasted with no salt added, they have a rich, creamy texture and milk flavor that often defies description. Ironically, the outer shells that originally protected these precious nuts are so hard it takes over 300 lbs. of pressure to crack one.
