National Macadamia Nut Day on September 4th recognizes a delicious nut found in many baked goods and desserts.

Delectable macadamia nuts have a creamy buttery taste. These nuts add a subtle richness to everything they grace. Also versatile, macadamia nuts originated in Australia. They were named for the physician and chemist, John Macadam, who discovered them. Macadam also pursued furthering the cultivation of the tree in Australia, making it more abundant.  

Similar to large evergreens, the macadamia tree grows between 30 and 40 feet high. Although they are native to Australia, most of today’s world supply grows in Hawaii. Growers first began cultivating macadamia trees in Hawaii in 1921. Indonesia, South Africa, and California also grow this delicious nut commercially. 

When is National Peanut Day?

Like many nuts, macadamia may be eaten raw or roasted. Bakers particularly like to use them in baked goods, such as cookies. They pair exceptionally well with chocolate, too.

Since the macadamia is nutrient-rich, they are known for their health benefits. But, of course, being in the nut family has its benefits, too! Macadamias are a valuable energy source, high in dietary fiber, gluten-free, high in mono-unsaturated fat. They also provide an excellent source of minerals and contain many essential B-complex vitamins.
