I make our own pickled eggs. Pickled ham, ham hocks, and pigs feet, too. NONE of them involve urine, little boys, or Chinese ANYTHING.
Too many “pickled” producs (except, oddly enough, pickles) in stores any more is just something drowned in salted distilled vinegar, with a couple of hot peppers tossed in ‘for flavor/spiciness’. The modern versions don’t hold a candle to what my dad I bought & ate decades ago: all you taste now is the vinegar.
The real give-away is the “must be refrigerated after opening” statement on the label. REAL pickling was to preserve food without/before home refrigeration.
Come to think of it, except the pigs feet, most of the stuff he pickled for himself, too...sometimes whill half pickled himself on home brew. Oh, he also made WONDEFUL brewed root beer.
