Some people prefer to eat nuts that have had very little processing after being brought in from the field. Raw nuts are extracted from the shell and that is it. They are loose packed in a bag but free to move and breathe. These nuts should be stored in a refrigerator until consumed.
Macadamia raw chips are not always available and not in large quantity. People use them for adding to cereal or baking. They are the pieces that result when a kernel breaks into multiple smaller pieces.
