This recipie is closer to a South Carolina sauce since it is mustard based. I can’t be really specific with the amounts of the ingredients since I never measure them out. Just assume everything is “to taste.” Just add one thing at a time until you get it the way you like it. And I’m also going to assume that you want to use pork. I’m going to get lynched for saying so in the middle of cattle country, but pork is the only “real” BBQ in my book. Beef, while good, just doesn’t hold up to a good pork loin. The following is my derivation on my wife’s family recipie who has been making BBQ in South Carolina since time immemorial.
The first and foremost ingredient is mustard, just plain, boring, yellow mustard. If you want to add some honey dijon, that’s okay too, but don’t get too carried away with it. The second and the most secret ingredient is apple jelly. Just melt some in your sauce pan and add the mustard. You can adjust the sweet by adding more jelly or adjust the tang by adding apple cider vinegar or balsamic vinegar. Once again to taste. Next, add some onion powder, and garlic powder if you must but fresh crushed garlic so much better. Then some Worcestershire sauce. The next ingredient is a shortcut/cheat and that’s liquid smoke. Smells hideous, but really helps the sauce out in the long run. Then add red pepper flakes, cayenne, black pepper, chili powder, and maybe some cumin (but not too much).
If you want a BBQ rub for your meat, take a half cup of brown sugar, half cup of cider vinegar, about a quarter cup of seasoned salt, quarter cup of paprika, then cayenne, chili powder, onion powder, garlic powder, finely ground savory, mustard powder, little bit of allspice, little bit of ginger, little bit of finely ground thyme. Mix it all together. Lay out your cut of meat out on lots of plastic wrap. Score the meat with cross hatching no more than a quarter inch deep. Don’t get too carried away with it if you want to maintain the meat as a roast. If you are going to be shaving the meat later, then go crazy. Rub the paste all over the meat, wrap it up in the plastic wrap, then let it sit for at least 12 hours. Then you can smoke it over low to medium low heat for about an hour per pound. If you are using pork, you want the temp to be between 150 and 160. Sorry, I don’t I have my Farrenheit to Celcius conversion table nearby. Any thing more is going to be too dry if you want to keep the meat like a roast. If you are going to shave the meat, 160+ is fine, but don’t go over 165. Take the meat out, let it rest for about 15 minutes, then carve or shave to your heart’s content. Serve with the sauce on the side.
Some people might protest the use of sugar and salt in the rub saying it will dry the meat out. It does a little, but since the end result is usually just finely chopped or shaved meat, it doesn’t matter so much.
