Kimchi

Kimchi (김치 ), also transliterated as "kimchee", is a family of Korean vegetable-based pickles. They are a basic part of Korean cuisine, with many variants, although usually strongly flavored, featuring garlic and hot peppers. Kimchi is a key ingredient for Korean dishes such as kimchi stew and kimchi pancake and is often eaten by Koreans with ramen noodles and gimbap rolls. The side dish is generally considered very healthy due to its lactic acid bacterias, antioxidants, and high fiber content. Although it is widely accepted that the advantages of eating kimchi include improved digestion and bowel function, other benefits, such as increased immunity and reduced chance of cancer, are disputed due to contradicting studies or lack of concrete evidence. In 2008, the Health Magazine listed kimchi as one of the five healthiest foods in the world.

History
The kimchi has its roots in the salted vegetables that were preserved as a source of food during the winter months. This practice existed in China and Korea some 3,000 years ago, and its method was later transferred to Japan by the Koreans from Baekje during the Three Kingdoms Period. Accordingly it is theorized that the Koreans originally called the dish chimchae, meaning "the salting of vegetable." The name underwent several phonetic changes over the centuries, to timchae, dimchae, jimchi, and finally kimchi.

Kimchi was first mentioned in the historical texts from the Goryeo Dynasty, including guidelines and conventions that detailed a list of kimchi types that were necessary for ancestral rituals. The kimchi during this period generally consisted of one or two vegetables that were preserved in salt. A number of poems in the 13th to 15th centuries mention kimchi, indicating that it became considerably popular. A medical journal from this time period listed the vegetables that were mainly used to make kimchi, such as cucumber, wax gourd, garlic chives, curled mallow, lettuce, green onion, and radish.

By the early period of the Joseon Dynasty, kimchi had evolved to contain various seasonings, which were first mentioned in a poem written by Seo Geojeong. The red pepper, which was introduced from Japan in the early 1600s, was not used as an ingredient until the mid-18th century. The cabbage kimchi that is most prevalent today was first mentioned in an agricultural guide from 1766.

"Summer kimchi" is made from leaves and cores of the cabbage family, while "winter kimchi" is based on white radishes of the daikon family.
