dougk,
Jerky is a food of LOVE, so I don't believe in recipes, but I'll tell you the basics as they have stood in my family. 1st-ground is for chili, not jerky. 2nd-use a soy sauce base and try to NOT get the authentic stuff, it is much more bitter than our A-merican version. Not sure what part of the country you're in, but Kroger brand is great. From there it goes by your personal taste, but I will tell you what I usually use. 1lg bottle of soy sauce, 1/4 cup of both worstcheshire sauce and teriyaki. 1 cup brwn sugar, lots and lots of garlic, red pepper, and onion powder. A little white pepper and black pepper. Now, I like it HOT, so I also at 1 lg habanero pepper carefully chopped. I also use Louisiana hot sauce for some tang. You can add more brown sugar and less pepper for more sweet and less heat and vice versa. This is a POTENT marinade, you should start taking it out after 1-1 1/2 hrs. Works in both dehydrator and oven. It's done when you can bend it and the outside cracks and you can see white fibers along the break. Good luck.
