RE: Cooking jerky in the oven....
We use jerky drying racks and do it like that. The drying racks come in a set of 3 and they stack up. They're sold in Cabelas.
I dry mine at 200 with the door open a crack. It dries in 2-4 hours depending on how much you have in. I have 2 sets of racks and can do about 6lbs.
You can dry it at 175 or so, but it takes longer.
