That and finding jerky that is just beef and salt is near impossible. Full of fillers, additives, and flavoring.
I'm not sure why anyone pays for beef jerky.
It is so easy to make, even I can do it.
We bought a $30 cheap dehydrator at Ollies. https://www.ollies.com/
Buy some Top Round at Sam's Club or HEB.
Cut it up, use salt and/or pepper. Let it geaux all night long...
