It is rumored that they were one of Cleopatra’s prized beauty secrets. They make apperances in the Bible and in Shakespeare’s writing. Pregnant women have been known to crave them along with ice cream. Pickles have been around for thousands of years, dating as far back as 2030 BC when cucumbers from their native India were pickled in the Tigris Valley. The word pickle comes from the Dutch pekel or northern German pókel, meaning salt or brine, two very important components in the pickling process. Throughout history pickling was a necessity, as it was the best way to preserve food for a long period of time. As one of the earliest mobile foods, pickles filled the stomachs of hungry sailors and travelers, while also providing families with a source of food during the cold winter months.
Pickles are created by immersing fresh fruits or vegetables in an acidic liquid or saltwater brine until they are no longer considered raw or vulnerable to spoilage. When we think of pickles, cucumbers commonly come to mind. Pickled cucumbers are often lacto-fermented in saltwater brine. During this process lactic microbial organisms develop, which turn the naturally occurring sugars of foods into lactic acid. In turn, the environment becomes acidic quickly, making it impossible for any spoiling bacteria to multiply. Cucumber pickles can also be made with a salt and vinegar brine, a popular choice for home cooks. The brine, known as pickle juice, is sometimes used by athletes to treat dehydration, though it has yet to be proven as a true remedy.
Kosher dills have a unique history of their own. In The Book of Jewish Food, Claudia Roden explains that pickled vegetables were a dietary staple for Jews living in the Ukraine, Poland, Lithuania and Russia. The sharp flavor of pickles proved a welcome addition to the bland bread-and-potato diet of these cold weather countries. For several generations, it was an autumn custom for Ashkenazim to fill barrels with cucumbers, beets and shredded cabbage. The mixture was left to ferment in a warm place for several weeks, then relocated to cool, dark cellars. The pickles would last through the long cold winter until spring, when new crops of fresh produce were available.
When a heavy influx of eastern European Jews arrived in New York City during the late 1800s and early 1900s, immigrants introduced kosher dill pickles to America. Cucumbers were washed, then piled in large wooden barrels along with dill, garlic, spices, kosher salt and clean water. They were left to ferment for a few weeks to several months; shorter fermenting time produced brighter green half sours, while longer fermentation resulted in full sours. Pickles were sold on pushcarts in the immigrant tenement district of New York City. Over time, Jewish-owned shops selling pickles straight out of the barrel began appearing in droves. Eventually, pickling became a profitable business within the Jewish community. Today, a plate of pickles is usually served complimentary with a meal at the best Jewish delis.
Home pickling was made much easier and more sanitary during the 1850s, when two essential canning tools were invented. First, a Scottish chemist by the name of James Young created paraffin wax, which helped to create a seal for food preserved in jars. A few years later, John Mason developed and patented the first Mason jar. Mason’s jars were made from a heavyweight glass that was able to tolerate the high temperatures used in canning and processing pickles.
Of course, pickles aren’t limited to the dill and cucumber variety. They can be sweet, sour, salty, hot or all of the above. Pickles can be made with cauliflower, radishes, onions, green beans, asparagus and a seemingly endless variety of other vegetables and fruits. When the English arrived in the New World, they brought their method for creating sweet pickles with vinegar, sugar and spiced syrup. Eastern Europeans introduced various forms of lacto-fermented cabbage, known as sauerkraut. The French serve tiny, spiced cornichons with heavy pâtés and pungent cheeses. In the Middle East pickles are served with every meal, from peppers to olives to lemons. Russians pickle tomatoes, among other things. Koreans have their kimchi, the Japanese pickle plums and daikon, and Italians pickle eggplants and peppers. Each area of the world has its own beloved variety of pickle.
