What You Should Know About Macadamia Nuts

With their thick, dark brown shell, macadamia nuts are externally reminiscent of our chestnuts. However unlike chestnuts you almost never see the macadamia nuts' shell, as they're so tough they require a special machine for cracking. This makes macadamia nut cultivation extremely complex, and the most expensive nut in the world to produce, which is often included in its price.


Macadamia trees originate from the rainforests of Australia, where native aboriginals have valued them as particularly nutritious and have consumed them for generations. It wasn't until the mid-1960s that Australia began exporting them. 


Since macadamia nuts are almost exclusively sold shelled and vacuum packed or canned, they are available all year round. The Australian harvest runs from March to June; in Hawaii the harvest is from September to December.


The soft, cream-colored nuts taste slightly sweet, intensely nutty and buttery. They have a crunchy but comparatively soft texture.
