This recipe is for starting with 1 pound of meat. You'll end up with about 1/2 pound in the end. You can easily double/triple/etc this recipe for large quantities of meat, however 5-6 pounds is about all you can fit onto a Nescao Snackmaster Pro fitted with 12 trays (the unit comes with 5).
NOTE: The package for the Eastman Outdoors jerky seasoning states that it makes up to 5 pounds of jerky. I personally feel that the flavor is too mellow, so I use just about an entire package for 1 pound of jerky. I end up with a little left over seasoning, which I store in a labelled air-tight container. I'll eventually mix it with more seasoning. I think I can get 3 pounds of well-seasoning jerky out of two packages of Eastman Outdoors mix.
