Ring of charcoal............ I'll give that a try.
I may be a little over careful but we usually use a commercial kit for our jerky so that it gets a cure. We freeze it for long term storage and, as said earlier, have found that when thawed the jerky becomes more even textured and chewy. Some of this batch will be in the mail for nearly 3 weeks so I want it to have a cure.
Most commercial kits don't have the desired yin/yang so we normally add cherry preserves for sweetness and cayenne pepper flakes for heat along with soy sauce, worcestershire sauce, black pepper and maybe granulated garlic. Sometimes even salt.
I check for the cure by cutting a thicker piece of meat and then it is easy to see if there is uncured meat still in the center of the slice. When I think that I may have it spiced right I'll cook a piece in the microwave until it is pretty dry. This is just so that I can tell if the spices are right. I usually end up adding more pepper flakes because we like our jerky with a little heat.
It seems like we adjust it a bit more after the first batch is dry too.
re-cap-
1) I use a commercial jerky kit and pretty much follow the directions.
2) I add some sweetness, brown sugar or cherry jam. I think ground up apricot preserves would work great. I think the sugar content makes the jerky chewier and I like it chewy.
3) Add some heat, cayenne, Tabasco, and/or black pepper. (gotta have that sweet/sour effect)
4) Test a piece with your microwave. If you put too much spice in then there is not much that can be done so work up to your personal tastes.
5) Dry at 190 deg or less until it is the way you like it. I like it pretty dry but not brittle. It takes eight to twelve hours in our oven. If your over is too hot you cook your jerky instead of drying it then it will not be chewy and it really is not jerky. Keep the oven 175-190 deg but not over 190. Jerky can be dried in the sun. The oven was on for over two days straight to dry 20 pounds. I could get about four pounds drying at one time. Two pounds per oven rack with the meat slices touching each other but not overlapping.
Every batch is different be it chili or jerky.
(There is usually enough salt in a commercial mix but not always. Sometimes a little liquid helps with getting everything blended, I use vinegar or soy or worcestershire sauce for this. Drier is better so it doesn't drip all over the oven.)
