Grandmama's BBQ Sauce

If you know my family, you know we are pretty famous for our rib cookouts.  Well, my Granddaddy is famous for his ribs and Grandmama is famous for her sauce.  I went on and on about it before The Jason ever met my family.  I think he didn't believe me that they are really so good!  Until he had them...then he was a believer.  This is my Grandmama's BBQ Sauce.
