What does AAA prime rib beef jerky taste like?

My previous question I would eat it quickly so I shouldn’t worry about it going rancid.

It tastes like beef jerky.

Using an excellent cut of meat for such a process destroys the reason one pays a higher price for a better cut and grade. Don’t waste your limited income on ruining expensive meat.

in my area costs Jerky about $10 US for 4 ounces (not prime). If you going to make your own it helps to have a delicatessen rotary slicer to get uniform slices. You’ll also need an oven that can hold 170* F or a dehydrator.
Maybe you can find another source; my COSTCO has Kirkland Premium Cut Steak Strips Dried Beef Jerky. It is uniform tender all the way through and easy to chew.

It tastes like salt, just like it all does.

Not really much point in using tender prime meat for something that is, by design, tough and dry.
