Cut the tenderloin in half lengthwise twice so it is in long, quartered, strips. Set these strips on a baking sheet and place in your freezer for two hours to firm up.
Slice your meat into ⅛" thick strips, or as thinnlyas possible.
Mix together all of the marinade ingredients in a small saucepan. Bring to a simmer and cook for 5-10 minutes, or until all of the brown sugar has been dissolved. Then remove from the heat and cool completely.
Once cooled, pour the marinade into a large sealable bag with the sliced pork. Let marinate overnight, or at least a minimum of two hours.
Remove pork from the marinade and pat dry. Lay strips of pork evenly on dehydrator trays and set the dehydrator to 160 degrees.
Dehydrate for four hours, or until the pork jerky dries out.
Store in an airtight container in a cool dry place.
