Odd you havent seen it being from the south…but that’s probably for the better! It’s Steak Sauce. Meant to be put on steaks…it’s in all major grocery chains and usually on the tables at most restaurants serving any sort of a steak menu. Bottle is shaped like a Worcestershire bottle, but has a white label with a big A1 on it. I never cared for it so at this point couldn’t even tell you what it tastes like. If a steak needs a sauce, then it’s not a good steak.

With that said, i’ve seen it used as a marinade ingredient, or more complex sauce ingredient- so it’ll still have its uses.

It's a sauce you put on bad steak. Or you put on good steak if you want to ruin it.
