You guys are crazy and both of you are wrong. LOL
j/k - Eastern BBQ is very simple. Smoke Boston Butts for hours on end (12 + hrs at 200 - 225) until pulled pork is achieved. Pulled, chopped or sliced. Add in some Lexington style sauce (or serve on the side) and enjoy.
I actually love sauces and eat them in excess. Hot sauce, ketchup, honey mustard, soy, etc. etc. Love sauce.
Lexington sauce is a combination of apple cider vinegar, ketchup, water, salt/pepper, cayenne pepper, crushed red pepper, lemon juice, and sugar (I like molasses or maple syrup instead). Being a big fan of Texas Pete hot sauce I usually add in a liberal portion or it to my BBQ sauce as a kicker.
