Most folks like some sweet with their meat. However, good BBQ doesn't need any sugar. It really doesn't. Rubs don't need it, ribs and brisket don't need sweet sauces (ie.Texas and Memphis brisket and dry ribs), and a simple vinegar based sauce used judiciously is fantastic with good pulled pork shoulder. Here's a rub recipe from Gary Wiviott's book, "Low and Slow", called "Graduate Rub":
6 TB paprika
4 TB BP
3 TB Kosher
4 tsp Garlic p.
4 tsp Onion p.
2 tsp chipotle powder or Mexican chile blend (not chili powder)
2 tsp dried oregano
1 tsp cayenne
Eastern N. Carolina dip:
2 cups apple cider vinegar (or an ACV/white vinegar mixture for a little less twang)
1 TB dried crushed red pepper
Pinch of sugar
BP to taste
Bib Bob Gibson BBQ Vinegar Sop Mop: (Mix 24hrs in advance.)
6.5 Cup caramel colored (substitute white) vinegar
1/2 cup gr. cayenne pepper
2 TB salt
3 slices lemon
I'm smoking five slabs of spares tommorrow, and will only sauce a couple at the most.
