I love to can veggies in jars and make pickled okra or pickled eggs. 
My grandma is a pickler! She is always preserving the lifespan of any food you can think of. It taste good too!
Yes and pickled eggs extends the life of the food for consumption
Pickled egg
Pickled eggs are typically hard boiled eggs that are cured in vinegar or brine. As with many foods, this was originally a way to preserve the food so that it could be eaten months later. Pickled eggs have since become a favourite among many as a snack or hors d'œuvre popular in pubs, bars and taverns, and around the world in places where beer is served.
After the eggs are hard boiled, the shell is removed and they are submerged in a solution of vinegar, salt, spices
Pickling
Pickling is the process of preserving or extending the lifespan of food by either anaerobic fermentation in brine or immersion in vinegar. In East Asia, vinaigrette (vegetable oil and vinegar) is also used as a pickling medium. The pickling procedure typically affects the food's texture, taste and flavor. The resulting food is called a "pickle", or, to prevent ambiguity, prefaced with "pickled". Foods that are pickled include vegetables, fruits, meats, fish, dairy and eggs.
