Actually, there's no recipe. This is too simple and too good it's
almost obscene.

Charcoal grill, (why burn up gas?)

1 bread pan

1 pork loin that fits perfectly inside the pan

Got the grill hot, put the loin in the bread pan, and fill the pan
with the marinade so that the meat is fully or almost fully covered.

Cover the pan with tin foil, and poke a couple holes in the foil. Put
it on the grill and close the lid. let it sit and boil for a while,
check it occasionally and when the liquid is about clear, then it's
ready.

remove from the grill and place the loin on a platter. cut the loin in
the serving sizes you prefer and cover the slices with the liquid.
You'll find the pork is surprisingly tender.

Serve it up and enjoy a treat.
