That is interesting to think about! There seem to be so many local brands that I’m not sure which ones are “name brands”. I think of Hunt’s and Heinz. Maybe KC Masterpiece, Stubbs and Sweet Baby Ray’s? A local brand around here is Kinder’s. When it comes to Alabama white, North and South Carolina styles, are there national brands?
An Eater link in another thread says there are about 5 “types”, and various brands of that “type” include the same ingredients.
