"Best Mac Nuts from Hawaii Living in Hawaii, I find it's not hard to appreciate macadamia nuts. After moving to the Islands, I did not waste any time determining my favorite kind of chocolate-covered mac, Mauna Loa. As with many other companies, mac nut orchards dot the Big Island, which has a great growing environment for the unusual nuts. The Mauna Loa Macadamia Nut Company operates a visitors' center on the Big Island along with their orchards and processing plant. A tour of the area includes a farm to final product education and, of course, free samples for your enjoyment. I always keep several boxes on hand to give to my house guests to welcome them to Hawaii, but mac nuts are also a great gift for tourists to bring back home."
