Basic Barbecue Sauce

I used this barbecue sauce recipe and the variations as a template for creating my own sauce. To begin with, I thought 2 cups of ketchup would be way too sweet, so I ended up using 1 part ketchup, 1 part tomato paste, 1 part hoisin sauce and 1 part stock. I also added a little bit of this and that (Worcestershire, mustard, bourbon, hot sauce, vinegar) until the sauce tasted really good to me. So while I ended up far afield of Bittman's simple sauce, this was the foundation for it.
