Finishing sauce for pork. Equal parts good quality apple cider vinegar, dark maple syrup, frozen apple juice concentrate. I use my apple juice can as my measuring cup. To that I add 3 tablespoons of my preferred pork rub, for me smokehouse maple. 1 TBS liquid smoke, tsp black pepper, 2 TBS dried mustard, 1 TBS onion powder, 1 TBS garlic powder, and 2 TBS red pepper flakes. I bring to a boil then let sit, and then bring back to a boil and let sit until ready to serve. At serving bring back to a boil and strain out all the pepper flakes and anything that people might think will make it spicy. Add to taste to the pork as you pull. I use a couple cups per pork shoulder. I also put some in a squeeze bottle for those that want a little more. Keeps the meat moist...
