I am new to smoking meats. I have always wanted to make my own beef jerky. I thought for my first attempt, rather then follow a homemade recipe I would by hi mountain mix. It calls for a cooking time of 2 hours at 200 f. It came out perfect! I would like to start experimenting with my own recipes someday but my question is every recipe I see has a cook time of 6 to 8 hours. Why is hi mountains only 2 hours? It turned out excellent compared to store bought! What's the difference?
