If you would like to make jerky with a food dehydrator,it isn't that hard and for the price of a video game you can buy one,or visit a flea market as I have seen food dehydrators sell for $10 or less.
It's a jerky machine. If you like to buy your jerky at the market, you know it's pretty expensive. It's just meat without the water. You can do that at home, and I think it's the main reason people buy food dehydrators. Of all the dehydrator recipes online, the most common are the jerky varieties. With a dehydrator at home, you can experiment. Instead of beef, how about trying venison, turkey, fish.
