I ate one of those pickled turkey gizzards once. It wasn't bad. It had the texture of liver. Would I eat one again? No.
And I was talking about regular hard boiled eggs, not pickled.
Before small sized snack foods got so popular, bars around here, even those who ran full service kitchens, would have hard boiled eggs, swiss cheese and pepperoni sitting in jars on the counter that people would buy as a snack. I even remember eating Easter eggs as a kid that simply sat in a basket until they were gone.
Of course, this was back in the day when we carried bologna and mayonnaise sandwiches to school in a tin lunch box and they sat at room temp for hours before eaten... or lukewarm soup.
I'm guessing the lack of preservatives would make one want to use up homemade mayo more quickly than store bought. Or at least not practice what we did forty years ago.
Give us this day our daily bacon.
