National Macadamia Nut Day

National Macadamia Nut Day is observed every year on September 4. Known as the “Australian pearl,” macadamia nuts are treasured by food lovers and chefs around the world. While macadamias have been enjoyed by Indigenous Australians for thousands of years, their popularity continues to grow in gourmet kitchens everywhere.

History

The macadamia tree, native to Australia, is part of a small genus containing four species. Although now grown in many parts of the world, macadamia nuts are still considered rare and valuable. The tree’s nuts are beloved for their buttery flavor and are often featured in cookies, baked goods, and even beauty products. Interestingly, macadamia trees were first cultivated outside Australia in Hawaii to protect sugar cane crops—not for their nuts! The name “macadamia” honors Scottish chemist John McAdam, though Allan Cunningham was the first to bring the nut to Europe in 1828.
