our the nuts into a glass bowl.

Add the salt to the bowl.

Fill it with enough water to cover the nuts.  They'll absorb a decent amount of water, so ensure you add enough (you can add more later if needed).

Allow this to sit overnight, or about 12 - 18 hours. (There is one exception -- cashews.  They shouldn't be soaked longer than 7 hours.)

The next day, pour the water off and rinse the nuts several times until the water is clear.

Then spread them on a dehydrator tray.  If you don't have a dehydrator, you can spread the nuts on a tray and put them in your oven as low as it goes (mine goes to 170ºF).  It won't preserve the rawness of the nuts, but it works.

Put the tray into your dehydrator (if you have one). Dry at 115ºF (which will preserve the rawness) for several hours until crisp.  It will only take 2 - 3 hours in an oven; it may take 12 or more in a dehydrator.
