Our friends cooked tenderloin in a heavy cast iron pot with cover on a wood fire. There was one ham cut in half and two tenderloins. NO WATER.
Cooked slowly over coals. After cooled he "slivered" them with a fork. So tender and pulled apart easy. Then he added the shredded cabbage (all done in the plastic bag) and some other seasonings. He mixed it all together. Tortilla wraps. They were delicious. Lots of work...but delicious.
