This might be the easiest recipe on the face of the planet. You need three things and one crockpot and lots of time.
Take 1 Pork Roast and rub liquid smoke all over it. Stick it in the crockpot on low for 12 hours. When it pulls apart with a fork, add a bottle of your favorite BBQ sauce and WHAMO, you have pulled pork sandwiches complete with the bits of burnt ends.
Really, you need no other liquid. Just the liquid smoke. I've done this many times and it turns out mouth watering every time.
I will mention that sometimes it's done sooner then 12 hours but never goes over.
I am making it this month, so I will grab pics for you this time.
