Home Processing Steps

Husking and Drying

First, take off the outer husk from each macadamia. Use a hand tool or a small husker for this. After husking, dry the nuts in a place with good air flow. Drying stops mold and makes shelling easier. Let the nuts dry for at least two weeks.

Cracking and Roasting

When the nuts are dry, put them in the shelling machine. Change the settings for the size of your nuts. The machine cracks the shells and takes out the kernels. After shelling, check the kernels to see if they are good. You can roast the kernels in an oven at low heat to make them taste better. Roasting also helps the nuts last longer.
