The simple definition of sauerkraut is fermented, salted, shredded cabbage. It is the oldest form of cabbage preservation and is still a diet staple in many countries. Sauerkraut, which means soured cabbage, is called by other names in many countries, but was brought to the United States by German immigrants and is best known by that name.
History
Although fermentation of cabbage can be found in written records as far back as the 1st century A.D., modern sauerkraut methods date back to the Middle Ages and have been steadily improved on since that time. Once a staple in most farmers' kitchens, today only a few groups of farmers, particularly the Amish and Pennsylvania Dutch, continue to make fresh sauerkraut at home.
Significance
Sauerkraut is high in vitamin C and iron. European medical experts recommended sauerkraut in areas where natural sources of Vitamin C could not be found. Because of its long shelf life, it was a perfect food to carry aboard long sea voyages.
Function
Sauerkraut is often served with pork or chicken. It is a traditional side dish served on New Year's Day and is a required ingredient in a Reuben Sandwich. Sauerkraut can be served raw or cooked, although the raw form has the most health benefits.
Identification
Sauerkraut can readily be identified by the smell. The sour distinctive odor can be overbearing if the food is allowed to stand uncovered for any length of time. The aroma gets even stronger if cooked and may take hours to dissipate from the area where it was prepared.
Misconceptions
Cole slaw is often confused with sauerkraut. Both are made with raw cabbage. The difference between the two is that cole slaw has added vinegar for the traditional acidic taste and sauerkraut is naturally fermented to give it a distinctive flavor and smell.
Benefits
Depending on how it is processed, sauerkraut can be considered either healthy or not healthy. Prepared the old-fashioned way with nothing more than salt, it is a source of both vitamins and minerals. Many new processing procedures include the use of nitrates, which can lead to health problems ranging from headaches to stomach cancer.
Warning
For those not used to eating acidic foods, it is recommended that you begin with small portions to prevent stomach upset.
