Tried & Tested - 7/5/07 - I made this yesterday  on the fourth, Everyone raved about how good it was. My best friend even asked if I would give her "my recipe" for her Labor day cookout!  I added an extra tablespoon of flour and a extra dash of sugar. I made it ahead of time,  and placed it in the oven one hour (225ºF.)before we sat down to eat.  I also made the Baked beans, they were great! TB Newport News, VA
