Pickling is the process of expanding the lifespan of food usually combined with another method, such as fermenting, canning, or just refrigerating.Pickled beet eggs are count to be as a British Classic. Boiled Eggs submerged in a jar kept on fermenting herring below a brine of salt , spices, and other seasonings. A big jar of beet-pickled eggs anchors many a neighborhood bar in Pennsylvania, which is bright in both flavor & color. I prepared Eggs-mimosa/Deviled-Eggs infusing traditional flavor of "Kasundi" into the red pickled eggs. Kasundi is a yellowish sauce prepared with fermented mustard with some spices.
