NC bbq is the only bbq- only argument to be made is eastern vs. western.
Eastern- whole hog, no tomato in the vinegar/sugar/pepper sauce
Western (or Lexington) - shoulders/ boston butts (only yankees would name a part of a shoulder a butt- go figure), and sauce is basically the same but with tomato paste sauce or ketchup added.
Rub the butt or shoulder with salt the night before- put back in the refrig. For the ignorant hicks down here, what exactly is "kosher" salt??
Heat coals on charcoal grill or cooker and tighten dampers to keep around 225. I usually put the meat off to the side of the fire over a drip pan tilted to slowly run back onto the edge of the coals to burn the drippings slowly. Add Kingsford coals and soaked wook chips (hickory, oak, apple, pear- anything but pine or mesquite) as needed to keep temp and smoke going. Or use real wood coals, but charcoal is easier to regulate and an approved cheat in real NC bbq BUT NO GAS.

When internal temp is 180-190 you're good to go. The old-timers can tell by twisting the butt and seeing how loose the meat is around the bone- I still play it safe with thermometer.
Chop or pull meat leaving in a little fat and amount of skin you prefer, drizzle with sauce and enjoy with hushpuppies, slaw, beans and sweet tea.
I smoked two butts Sunday and it took about 9.5-10 hours this way.
Coke, liquid smoke, gooey store sauce....


must be a yankee thing...
J.K. guys- all like it their own way but that's how to do authentic NC bbq- hope this helps.
