I didn't really follow a recipe, although I looked through many online. A lot of people like to use flank steak or round steak. I used Round Roast, but from what I've read just about any cut of beef will work, just make sure there is as little fat as possible in the meat. From what I gather you pretty much put what sounds good to you in the marinade. Here's what I used:
Soy Sauce (this was the main ingredient for my marinade)
Worcestershire Sauce
Salt
Pepper
Garlic Powder
Crushed Red Pepper Flakes (to make it spicy)
Trim as much fat ass possible off the meat. Cut your meat into 1/8 to 1/4 inch slices.
Marinade as long as you want. Some people say to marinate overnight, others say 6-8 hours. On my first batch I marinated it for 30 minutes, and it tasted great. The second batch I marinated it for 2 hours, and didn't notice a difference flavor wise, the main difference I is the second batch was spicier because it had more time with the crushed red pepper.
Depending on how thick your jerky is, as well as how dry you like it, will depend on how long it needs to dehydrate.
I did the first batch for 11 hours. The second batch I accidentally went to long, about 13 hours, so it was dehydrated too much. It's still edible it is a lot easier to tear and will be chewy once your start chewing it.
But if you find you've dehydrated it more than you like I found a trick online that I tried and it works!:
Take a piece of bread and put it in the center of a zip-lock bag with the beef jerky around it and leave it overnight or until the jerky is how you like. The jerky will absorb the moisture from the bread. The bread will be dry like toast when you take it out.
