Love jerky, my son constantly asks for it while shopping. Since it is so expensive I made him a deal one time, we bought some fajita beef strips, pineapple juice and soy sauce and I had him help me make jerky out of it. Of course we had to cut it thinner, marinate it in the fridge overnight, but when it was done, he rarely asks for jerky from the store unless he wants it right then.
He loved it, whenever I make anything in the dehydrator, it rarely lasts the week. I can't make enough to store as they treat it like candy. Same when I make banana bread.
