It’s usually the German settle areas that end up with a mustard based sauce. South Carolina has it too, that’s the only barbecue I’ve ever met that I don’t like. It’s not the sauce, it’s the soggy pulp they make of the pork that puts me off.
Then there’s Alabama white sauce. Awesome ribs, very mundane origin of the sauce, beginning with mayonnaise. Don’t knock it till you’ve tried it though, lol.
It’s all good to me.
I hate samo samo, I love local color.
