When I make bbq pork i do the pork tenderloin,
a couple cups of water (enough to cover the meat)
and put in a bunch of spices - brown sugar, cumin, chili powder, salt, pepper, old bay, thyme, tabasco sauce, whatever looks good.
I use all of those.
Add way more sugar than everything else (the ratio I shoot for is like 6 or 8 to 1).
Then when it's done I shred it with two forks, stir in barbeque sauce (something you like)
and serve on warmed or toasted hamburger buns.
