My favorite barbecue sauce is the tangy Carolina style. It has a vinegar base and it's quite tangy. It's hard to find around here but there's one place that has it: Georgia South Barbecue in Barnesville, GA. I like to get up there when I can because they also have great Brunswick Stew.
We found these chips in Kroger tonight and they taste like taking a plain Lay's chip and dipping it in their stew. They're awesome.
