What are pickled eggs?
Hard-boiled eggs marinated in vinegar and pickling spices, spicy cider, or juice from pickles or pickled beets.
Unopened containers of commercially pickled eggs keep for several months on the shelf. After opening, keep refrigerated and use within seven days. Home-prepared pickled eggs must be kept refrigerated and used within seven days. Home canning of pickled eggs is not recommended. Although the acidity of the pickling solution is usually sufficient to prevent the growth of bacteria, it eventually causes the eggs to disintegrate.
