Kimchi is a Korean side dish made with salted and fermented vegetables. This Korean staple side dish usually has cabbage, radish, garlic, ginger, and various seafood, with spices and seasonings. In the past, kimchi was stored in jars and buried in the ground to stay at a certain temperature suitable for fermentation. However, these days, kimchi can be preserved in the refrigerator. There are hundreds of kimchi varieties, depending on the ingredients. However, it usually contains cabbage and radish. It is a low-calorie but very spicy condiment that contains a lot of fiber. It is served with every meal, usually with rice, fish, potatoes, or noodles. However, kimchi can be added to any food, such as pizza and hamburgers, soups, stews, sandwiches, and even pancakes. It is estimated that each Korean eats about 40 pounds (20 kilos) of kimchi a year.
Kimchi is fermented at low temperatures and then mixed with chili pepper, garlic, ginger, radishes, and spring onions. Its color is red because it contains chili peppers. Today, Koreans cannot imagine a diet without kimchi, along with rice and soy.
In ancient times, kimchi was called “ji,” or in Korean, “dihi.” Today, the term “gimchi” is accepted in North and South Korea. The name was derived from the word “shimchae,” or salting of vegetables, which was a logical translation, considering the way it is made. Kimchi is the national dish of North and South Korea. This Korean staple dish dates back to the period of the Three Kingdoms (57 BC to 668 AD), but it didn’t contain garlic or red peppers before the 16th century. Koreans started to make kimchi because it was impossible to grow vegetables during winter. Adding chili peppers to kimchi became widespread in the 19th century. The noted kimchi recipes from the 19th century are very similar to today’s kimchi recipes. Nowadays, kimchi is prepared using the same ingredients but with a modern fermentation method, that is, using a kimchi refrigerator.
Kimchi's most important ingredients are cabbage and radish. For the cabbage, Napa cabbage, headed, and bomdong are used. The radishes used are mainly the Korean, young summer, gegeol, and ponytail radishes.
Other kimchi ingredients that may be used are the following:
- Chili peppers
- Korean parsley
- Perilla leaves

It is an unwritten rule that kimchi should have five tastes: sweet, salty, sour, spicy, and bitter. There are a lot of variations of kimchi, but every kimchi usually contains chili peppers and garlic, which are in charge of giving it its spicy taste and fine aroma. Kimchi should be kept in the fridge and eaten within a period of one month after opening a jar.

Kimchi health benefits
