I do a lot of jerky, but mostly with beef. For the "Slim Jim" type jerky, I use American Harvester spices which come in a package of seasoning and a package of "cure". You use one pack of each for a pound of meat.
I personally do not like the texture of ground turkey.
With turkey, I buy a turkey breast, freeze it partly and use my meat slicer, cutting the pieces ACROSS the grain, about 1/4 inch thick. Then I marinate the meat overnight in a ziplock type bag with soy sauce, worchestshire (?) sauce and teriyaki. I use the same procedure for beef roasts.
I dry all of them on my American Harvester dehydrator for about 6 hours at the maximum heat. I turn both types at least once during the drying process and blot the grease with paper towels.
On the turkey, I was worried about samonella, so I take the dried slices and put them on a cookie sheet and put them in the oven at 500 F for about 10 minutes. This also tends to give the turkey a bit of a smoke flavor which I really like.
You can get the American Harvester at the big box superstore or order from on line.
I make about 8 lbs of jerky every weekend.
