Soaking in soy sauce or teriyaki sauce is a favorite. A mixture of salt, pepper, oregano, marjoram, basil and thyme is tasty. Many seasonings work well. It is a personal preference. Dry seasoning mixtures need to be pounded into the meat for best results.
Many people enjoy jerky with a lot of pepper.
You will need to experiment to find your favorites. Preheat your oven to 120 degrees. After the meat is seasoned, spread the meat evenly on wire racks in the oven. Try not to have the meat pieces touch each other. You can use metal racks other than the oven racks with a cookie sheet underneath to make cleanup much faster.
