Here in N.C we use a vinegar base sauce I was wondering would it be ok to inject the butt when it 3/4 done to help keep it moist and add flavors. I do this all the time when I do a whole hog.
Well there's your answer. If it works when you do a hog, it'll work for a butt. Just think of a pork butt as a REALLY WELL TRIMMED whole hog. I can't see the process being much different. except for the lack of skin.I do this all the time when I do a whole hog.
