In a resealable freezer bag, combine all ingredients except for the meat.
Add the sliced meat, seal bag and massage gently to incorporate the marinade throughout the meat. Unseal just a small section, push as much air out of the bag as possible, and reseal. Let marinate for 30 minutes (on counter-top at room temperature is fine) or refrigerate up to overnight.
Lay out the meat in a single layer (as neat as possible) on the dehydrator racks. Set dehydrator according to manufacturer's instructions.
London broil is my favorite beef for this jerky.A deli slicer is a great implement for beff jerky but also versatile tool in your kitchen. Recently received a Kalorik Meat and Deli Slicer for review that's designed specifically for the home market. The unit is affordable at less than $100, and small enough to tuck away in the pantry. When marinading the beef in a plastic bag, unseal just a small section, push as much air out of the bag as possible, and reseal.Let the beef marinade for at least 30 mins.
