Take 1 lb of lean beef - I used round tip - and cut against the grain. You want the strips to be roughly 1/8" to 1/4" thick.
In a bowl combine the marinade ingredients in the specified quantities. Ensure the molasses and salt are well combined.
In a gallon storage bag, add your beef and marinade. Force out air and then roll the bag on top of itself. Then massage the marinade into the beef.
Put in your refrigerator and marinate overnight.
Heat Treat the Jerky
Line a baking sheet with aluminum foil. Then place oven-safe cooling racks on top. Put your marinated beef jerky on top of the cooling racks, ensure that pieces aren't touching or overlapping.
Pre-heat your oven to 350F.
Once pre-heated, put your beef jerky in the oven for 10 minutes.
While your jerky is being heat treated, set your dehydrator to 130F.
Dehydrating Beef Jerky
Once your jerky is done heat treating, place your beef jerky in your dehydrator. Ensure pieces aren't touching or overlapping.
Allow the jerky to dehydrate for 3 hours and then start checking for doneness.
Testing Beef Jerky
After 3 hours take a few pieces of beef jerky out of the dehydrator and allow them to cool for 5-10 minutes.
Once cooled, bend the jerky. If at the bend you notice a "spider webbing" - it's done. If at the bend you notice the jerky is rubbery and has hues of red/pink, it's not done.
Storing the Jerky
Once done, place in a ziplock bag with the top open and allow the jerky to aerate for 30 minutes. Once aerated zip the top and store in a cool, dry place.
