History:

The Macadamia is native to southeastern Queensland, Australia, where it grows in the rain forests and close to streams. The recorded history of the Macadamia began not until 1875 when British botanists were exploring the forest along the Pine River in Queensland. It is known, however, that Australian aborigines congregated during the months of Fall and Winter (March to June) in certain areas to feast on the seeds of two kinds of trees. One of the trees was called 'kindalKindal', now known botanical as the Macadamia.

Macadamias are large, spreading evergreen trees reaching 30 to 40 ft. high and almost as wide. Macadamia nuts have a very gard seed coat enclosed in a green husk that splits open as the nut matures. Mature nuts will fall to the ground from late fall to spring

Uses:

Macadamia nuts are considered by many to be the prime edible nut. It is also one of the most expensive nuts but enjoys growing popularity. Macadamia nuts are eaten raw or after cooking in oil are roasted and salted. Chocolate covered Macadamias are popular gift items at many airports in Hawaii and California.

Macadamias can also be used to make an edible bland salad oil.
