In almost any pantry, pickles are a staple. A wide variety of fruits and vegetables are preserved using salt and acid, although the classic cucumber has become ubiquitous enough to earn the simple default name of "pickle." Pickling is a preservation technique that dates back to ancient history. Every culture has its own version of the pickle, ranging from Mexico's pickled jalapeno pepper to Korea's kimchi. Pickles are often used as a flavor accent, garnishing a meal rather than acting as the main focus.
