22.1 North Carolina vinegar sauce
For pulled pork (well, smoked at least, but why wouldn’t you smoke it?), I don’t think anything beats the vinegar style sauce from North Carolina. There are a lot of small variations (some would complain about the ketchup in this recipe).
Source: I think I got this from MeatWave.
Ingredients:
Ingredients  | Tools  | 
3 cups apple cider vinegar  | Pot  | 
3 tbsp dark brown sugar  | Whisk  | 
1.5 tbsp ketchup  | Dressing container  | 
1.5 tbsp Texas Pete hot sauce  | |
1.5 tsp red pepper flakes  | |
1.5 tsp black pepper  | |
1.5 tsp salt  | 
Preparation:
- Put the ingredients into the pot.
 - Bring to a boil. Whisk regularly until the sugar and salt are dissolved.
 - Remove from heat and allow to cool.
 
Variations:
- Boiling longer seems to reduce the tartness a bit. It will also thicken the sauce slightly (not much).
 - Adjust the hotness by varying the amount of Texas Pete (or other tabasco sauce if you’re a savage), or red pepper flakes.
 
Notes:
- I use this OXO container, or at least something very much like it. Also available at Target. I think. At least it used to be.
 - Add some more Texas Pete and red pepper flakes by 50% for the recipe if you want it to be hotter. I’d start with another 50% of each.
 - Coconut sugar can be used in place of brown sugar in a pinch.
