I don't care to add any other ingredients to my product I make to cure other than MORTON TENDER QUICK CURING SALT. I have used this curing salt and also sugar but I prefer to refrigerate and freeze my jerky anyway for safety reasons. I have been making jerky and pulled pork for years, it’s very important to get the temperature right. To low of a temperature can be very dangerous. I smoke my jerky at 160 degrees and sometimes that temperature goes up and down with a real smokehouse like mine. It will creep up around 170 at times. One with two kids, well 23 and 19 not kids anymore it doesn't last very long if I have my jerky out. The question was how long I smoke the meat, smoke at 150 or as close as you can for 4 hours then I flip the jerky and smoke for 2 more hours. Turkey Jerky takes about 2 more hours than Deer jerky. I use Ash, Oak and Apple wood for my jerky ash for the heat Oak also is a good heat wood, Apple give great flavor to the Deer/Turkey jerky.
