Pickled pig's feet are available in almost every grocery store in the Deep South. Before the health nazis gained control of everything, there would be a big jar on the counter where you could fish out a pickled foot or snout, another jar for pickled eggs, and of course large, sour dill pickles. You hardly see anything like that anymore.
You know, I forgot about pickled pigs feet. Never ate one, sounded pretty awful and look just as bad as it’s sounds...lol And I remember pickled eggs and such, I had completely forgotten about that stuff. Like you said, you just never see that much anymore.
