The macadamia tree is one of Australia’s gifts to the world. While macadamia nuts are often associated with Hawaii, they’re actually native to the rain forests of Queensland, Australia. Macadamia nuts (sometimes called Queensland nuts) are named after botanist John Macadam, who first described the tree’s genus. Though they are grown throughout the world, Australia remains the world’s largest grower of macadamia nuts, producing approximately 40,000 tons of in-shell nuts per year. The white crunchy nut is one of the most desirable in demand treats.
