Take 1 lb of flank steak and cut against the grain. Slice the strips so that they're 1/8" - 1/4" thick.
In a bowl combine the marinade ingredients in the specified quantities. Ensure the molasses and salt are well combined.
In a ziplock bag or non-reactive container, add your sliced meat and marinade ingredients. Massage the marinade into the meat.
Marinate the jerky for at least 2 hours or ideally, overnight.
