Beef can be substituted for this but I like venison jerky the best. Start out with some backstraps. Any part will do actually.
Cut them into 1/4 inch thick slices.
Get your spices out
Dust them really good with garlic powder, cayenne, and a little salt.
Put them in a ziploc gallon bag and add a dash of lemon juice, some Worcestershire sauce, and some hot sauce. Put more garlic powder and cayenne in the bag too. Let it marinade overnight in the bottom of the icebox.
Put some tin foil on a cookie sheet or two depending on how much you are making and spray it very lightly with Pam. Spread the marinated backstrap slices out and dust them again with garlic powder and cayenne and a little salt.
Put them on the top shelf of the oven and let it go real slow at about 150 degrees. About an hour later turn them over and dust them again. Remove them while they are still pliable. I keep them in the icebox in a ziploc bag.
