Store bought jerky is alright. I like Jack Links, and a couple of other brands, but theres nothing like making it yourself. It tastes so much better. I love the fat, and store bought jerky just doesnt have any fat.
TurboRust's recipe sounds about the same as what I've used before, except I left out the Tabasco, red pepper and liquid smoke.
+1 for ostrich jerky
As a South African I am obligated to say that Jerky sucks balls, Biltong is better....which it is.
