When I started to make jerky, it was all trial and error with the salt until I got the right amount dialed in. IMO, the brine is what makes the jerky. Sometimes I'll experiment and make a kitchen sink brine, i.e., everything in the spice shelf and then some will go in. Sometimes not good, but other times ,WOW. Half the fun of making different jerky is experimenting with the brine contents and types of smoking woods.
The nice part is, if it walks, swims or flies, it goes in the smoker..
