Wikipedia: Pickled cucumber
A pickled cucumber (commonly known as a pickle in the United States and Canada, and a gherkin in Britain, Ireland, Australia, South Africa, and New Zealand) is a cucumber that has been pickled in a brine, vinegar, or other solution and left to ferment for a period of time, by either immersing the cucumbers in an acidic solution or through souring by lacto-fermentation. Pickled cucumbers are often part of mixed pickles.
