Slice the roast into your desired thickness and place it into a bag or bowl.Next, pour over the marinade and refrigerate for up to 24hrs.Once the jerky has marinated, place it onto jerky racks making it easier to get them on and off the smoker. We are going to smoke this jerky at 175° for 4 hours, or until our desired consistency. Be very diligent about checking the jerky near the end of the cook so you achieve your desired doneness.
