A "pickle" is a food item made by soaking vegetables, usually cucumbers, in a brine solution of salt and water, often with added spices. This process, called pickling, preserves the vegetables and gives them a tangy flavor. Pickles can be enjoyed on their own, as a crunchy snack, or used as a condiment on sandwiches and burgers. In addition to cucumbers, many other vegetables can be pickled, such as carrots, beets, and onions. Pickles are popular in various cuisines around the world, and they can be found in different forms, like dill pickles, sweet pickles, and bread and butter pickles.
