Macadamia nuts

At $25 per pound, macadamia nuts are the world's most expensive nuts.The nuts keep breaking price records every year. Macadamia trees take 7 to 10 years to begin producing nuts, and the nuts can only be harvested a few times a year. Although the demand for the nuts has largely outpaced the supply, exporters worry that a bubble in the global macadamia industry is about to burst.
