KC Masterpiece BBQ Sauce is my favorite. This recipe was found at http://www.cdkitchen.com (search on KC Masterpiece). Frankly I don't think it tastes like KC Masterpiece but it is an awesome sauce that I have used with baby back ribs, pulled pork, and brisket with excellent results.
Seal in water bath - 20 minutes for 1/2 pint or pint jars.
