Put nuts in a bowl.

Add salt and water.

Allow to soak at least 7 hours (or overnight).

Drain and rinse.

Spread onto dehydrator trays and dehydrate no higher than 150 degrees for 12+ hours until completely dried.

OR spread onto cookie sheets and roast in a low oven (as low as your oven will go) until dried and crispy.

Once they are thoroughly dried, you can store in an airtight container.
