You can make your own pork rinds.
I'm not sure exactly how, but i know that there are some here that do.
Maybe it would help if you had control of how they were made...as far as the salty taste is concerned.
Perhaps there is a thread?

I use pork rinds for endless things.
My alltime favorite is pancakes.
They are wonderful, and the pork rind batter is perfect even without any flours such as almond or flax!
I'm not a big fan of plain porkrinds for snacking anymore...but i love to use them in cooking.
