Pickles are preserved fruits or vegetables, typically cucumbers, that have been fermented or marinated in a solution of vinegar, brine, or a mixture of spices and seasonings. This process enhances their flavor and extends their shelf life. Pickles can vary in taste from tangy and sour to sweet, depending on the ingredients used. Commonly enjoyed as a condiment, snack, or side dish, they add a crunchy texture and vibrant flavor to a variety of dishes, making them a staple in many cuisines around the world.
