Kimchi is not just a dish, but a true symbol of Korean culture, which was added to the list of intangible cultural heritage by UNESCO in 2013. This pickled fermented cabbage with spices has become popular worldwide due to its unique taste and healthy properties. According to surveys, 95% of Koreans eat kimchi every day, and 64% have it with every meal. This dish has become an indispensable part of Korean identity and culinary culture, spreading far beyond the Korean Peninsula.

History and Cultural Significance
The origins of kimchi date back to ancient times — the prototype of this dish is mentioned in the verses of the poet I Kyu Bo, who lived in the period of 1168-1241. The first mentions of preserved vegetables in Korea date back to the period of the Three Korean states (37 B.C. to 7 A.D.), when Koreans began to prepare vegetables for winter through salting and fermentation.
Interestingly, the red chili pepper, which today is an indispensable ingredient of kimchi and its vibrant color, began to be added only after the 16th century, when it was brought to Korea by Portuguese traders. Until that time, kimchi was either white or yellowish, resembling pickled cabbage. The first recipes for kimchi with red pepper appeared in culinary books only in 1765, which testifies to the evolution of this dish over centuries.
In traditional Korean culture, there is a unique tradition of preparing kimchi called kimjang (kimjang). This ritual takes place in late autumn when the temperature drops to 0-4°C — ideal conditions to start the fermentation process. During this period, families, neighbors, and entire communities gather to prepare large supplies of kimchi for the winter. Different households share one secret recipe for preparation, while individuals contribute with hard work — transporting barrels and cabbage.
This ritual is an important aspect of Korean identity, which was also included in the list of intangible cultural heritage of humanity by UNESCO. Kimjang is not just about preparing kimchi; it is a time for strengthening family ties, sharing news, and supporting social cohesion. Traditionally, each family prepares 100-200 kg of kimchi, which ensures enough supply for the entire winter season.
In 2013, the Korean government officially recognized kimchi as a national dish, and the preparation of kimchi has become an integral part of national cultural identity. In South Korea, there is even a museum in Seoul, where visitors can learn about the history of kimchi, see over 200 types of kimchi, and even participate in cooking master classes.
Healing Properties of Kimchi
Rich Nutritional Profile
Kimchi is considered one of the healthiest foods globally due to its unique combination of nutritious ingredients. This low-calorie product contains approximately 41-47 kcal per 100 g, making it ideal for those who are watching their weight or maintaining a healthy lifestyle.
Kimchi is extremely rich in various beneficial nutrients:
Vitamins: Kimchi contains high concentrations of vitamin A, which supports healthy vision and skin, and vitamin C—an essential antioxidant that boosts the immune system. A single serving of kimchi can provide up to 50% of the daily recommended intake of vitamin C. There are also vitamins from group B (B1, B2, B3, B6, B12), which play a role in energy metabolism and help maintain the body’s energy balance.
Minerals: The storage contains calcium for bone density, zinc for wound healing, phosphorus for dental health, magnesium for the nervous system, potassium for cardiovascular health, and iron for immunity. Yeast and fiber enhance health and quality.
Cruciferous: Cabbage and other vegetables ensure a significant amount of dietary fiber, which stimulates gut peristalsis, improves digestion and promotes the elimination of toxins from the body. One portion typically contains about 2-3 servings of cruciferous vegetables.
Probiotics: During fermentation, beneficial bacteria like Lactobacillus plantarum, Lactobacillus brevis, and Leuconostoc mesenteroides develop in the strain. These probiotics support intestinal health and improve overall well-being.
Antioxidants: Red pepper is rich in capsaicin — a potent compound with antioxidant properties. The extract is used as an ally, while the fiber is beneficial. These substances protect cells from oxidative stress and slow down the aging process.
Impact on Health
Improved digestion and gut microbiota
During fermentation, over 200 types of beneficial bacteria are established, creating a genuine ecosystem in the gut. These microorganisms do not just populate the gut; they actively work to benefit the body. Probiotics help break down complex carbohydrates and fibers, enhance nutrient assimilation, synthesize essential B and K vitamins, and reduce symptoms of gastrointestinal distress, such as constipation and bloating.
Strengthening the immune system
The combination of antioxidants, vitamin C, zinc, and magnesium creates a powerful shield for the immune system. Vitamin C stimulates the production of white blood cells—lymphocytes, which fight infections. Zinc provides a synergistic effect with antibodies and antiviral properties.
Control of weight and appetite
Due to high cell content and low calorie count, which helps to feel satiety and control appetite. Cellulite builds up in the shank, creating a feeling of fullness that prevents overeating.
Reduction of cholesterol and heart support
Numerous Korean studies have confirmed that regular consumption of kimchi helps to lower levels of total cholesterol and lipoproteins of low density (bad cholesterol) while increasing levels of high-density lipoproteins (good cholesterol).
Control of sugar in the blood
Fermented products have a lower glycemic index compared to fresh vegetables, indicating more stable blood glucose levels after consumption. This is especially important for people with type 2 diabetes or prediabetes.
Support for mental health
Recent studies have revealed the existence of a “gut-brain axis”—a bidirectional connection between the gut system and the central nervous system. Probiotics present in kimchi may influence the production of neurotransmitters, such as serotonin and dopamine.
Protipokazannya and limitations
Noted numerous benefits that may be subject to certain limitations, which are important to consider:
High nutrient content: A medium-sized cabbage can contain a substantial amount of salt — it can have 400-800 mg of sodium in 100 g. Excessive consumption of salt can lead to elevated blood pressure, retention of fluid in the body, and increased strain on the kidneys. People with hypertension should limit their salt intake to 1 serving per day.
Gastrotic and adverse reactions: High levels of capsaicin may pose a problem for individuals with a syndrome of adverse reactions in the stomach, gastritis, gastric ulcers, or hemorrhoids.
Weight and breastfeeding: Women who are pregnant must take special care due to the high salt content and potential pathogenic bacteria when improperly prepared.
Histamine intolerance: Fermented products can contain histamine — a substance that can trigger headaches, migraines, or heart palpitations in some individuals.
Classic recipe for cabbage with Pekin cabbage
Ingredients
For the cabbage:
- 1 large head of Pekin cabbage (1.5-2 kg)
- 100 g of coarse salt (not iodized!)
- 1 liter of cold filtered water
For the rice base:
- 200-300 ml of water
- 15-20 g of rice flour
- 1 tbsp. of sugar (preferably brown)
For the gastrotic pasta:
- 40-50 g of red chili pepper
- 30 g of pasta
- 1-2 garlic cloves (6-8 teeth)
- 15-20 g of fresh ginger (pieces of 2-3 cm)
- 1 pear or apple
- 15 g honey
- 15-30 ml of vinegar sauce
- 2 tbsp. of soy sauce
For the vegetables:
- 1 large carrot (150-200 g)
- 100 g dried raisins (optional)
- 1 bunch of green onions
- 1 tsp. of mustard seeds (optional)
Pickling Process Preparation
Step 1: Preparing the cabbage (5-8 hours or overnight)
Select fresh, tight heads of Pekin cabbage without yellow leaves. Cut the cabbage lengthwise into quarters, making a cut from the top down to the center, and then carefully break it apart by hand. Chop each quarter lengthwise into quarters as well, resulting in 4 pieces.
Prepare the brine for pickling: dissolve 100 g of sea salt in 1 liter of cold water. Then, sprinkle the dry salt on each leaf of cabbage, especially on the thick parts. Leave the cabbage in a jar with salty brine, pressing down with a heavy weight, and leave it for 5-8 hours or overnight.
The cabbage is ready when the leaves become soft and easily bend. Rinse the cabbage under cold water 2-3 times, picking off each leaf to remove all the salt.
Step 2: Preparing the rice base (10 minutes)
In a saucepan, mix 200-300 ml of cold water with 15-20 g of rice flour. Place on medium heat and boil, stirring continuously, until you achieve a thick consistency (2-3 minutes after boiling). Add 1 tbsp. of sugar and leave to cool down to room temperature.
Step 3: Preparing the spicy paste (15-20 minutes)
Details in the blender: apple, ginger, and pear should be ground to a paste-like consistency. Grate the pear finely. In a large bowl, mix together cooled rice base, grated apple-ginger mixture, pear puree, 40 g of chili powder, 30 g of pasta, 15 g of honey, 15 ml of fish sauce, and 2 tablespoons of soy sauce.
Add green onion, pear puree, and daikon. Thoroughly mix all the ingredients — it should turn into a thick red paste.
Step 4: Combining cabbage with pasta (15 minutes)
Put on those rubber gloves! Take a handful of cabbage and gently press each leaf together with the paste, especially the white parts. Then place the cabbage in a clean glass jar, pressing it down with your hands so that the air comes out. Leave 2-3 cm of free space at the top. Cover tightly with a lid.
Step 5: Fermentation (3-7 days)
Let the dish stand at room temperature (20-24°C) for 3-7 days. Each day, open the jar for a couple of seconds to release excess gas that builds up. Short fermentation (1-3 days) gives a fresh taste, while longer (5-7 days) results in a more sour and intense flavor. When it reaches the desired taste, transfer it to the refrigerator.
Variations of Kimchi
Kimchi with Daikon (Kaktugi)
One of the most popular types after cabbage kimchi. Daikon is diced into cubes of 2-3 cm, salted for 30-60 minutes, then mixed with a spicy paste made of red pepper, garlic, ginger, fish sauce, and green onion. It has a crunchy flavor and can also be sweet. It ferments faster — 2-4 days at room temperature.
Kimchi with Beans (Oisobagi)
Freshly prepared garnishes with herbs add flavor to dishes such as pasta, salads, and fish. This is a light variant that is prepared faster (2-3 days) and has a refreshing taste. The garnished Kimchi lasts less than sauerkraut — up to 2-3 weeks.
Kimchi with Green Cabbage (Pak Choy)
People use whole stems of young green cabbage that marinate in savory sauce. This is a quick variant, ready for consumption within 1-2 days. The sauce is bright with a flavorful character of pungency.
Vegetarian and Vegan Kimchi
Instead of fish sauce, use soy sauce, miso paste or a special vegetarian fish sauce. Add radish to enhance flavor and depth of the sauce and imitate seafood accents.
Water Kimchi (Dongchimi)
This is primarily a different kind of kimchi — not fermented, mild, with a high quantity of ingredients. It is made with radishes and without red pepper and is flavored with a sweetened brine. It is fermented at a cool temperature. This refreshing, slightly tangy sauce is ideal for serving after juicy meats.
Important Tips for Successful Preparation
Selection of Ingredients
Salt: Use only coarse sea salt without additives. Iodized salt is categorically not suitable — it interferes with the fermentation process and can impart an undesirable aftertaste.
Red Bell Pepper: Korean bell pepper Kochugaru — these are special dried flakes with a mild sweetness and smoky aroma. If you can’t find it, be sure to substitute with dried red pepper in the blender, but not to the point of dust.
Time and Amber: Use fresh ingredients. The time should be still without green parchment. Amber — firm from fresh fragrant aroma.
Fish Sauce: Choose a quality sauce, where the first ingredient is anchovies. The simpler the composition, the better.
Fermentation Process
Temperature: Ideal temperature is 20-24°C. At higher temperatures (25-30°C) fermentation accelerates, but the flavor will be different. At lower (15-18°C) the process slows down.
Gas Release: Every day open the jar for 5-10 seconds to release excess gas. This prevents excessive pressure buildup and ensures even fermentation.
Encapsulation in the Jar: Ensure that all cabbage remains sealed in the brine. Parts above the brine can come into contact with air and spoil.
Sterilization: Each time you open the jar, use a clean spoon. Never insert directly from the jar.
Types of Salts and How to Use Them
- Using iodized salt: Iodine inhibits fermentation. Always use sea salt.
- Insufficient salting: Cabbage remains overly firm. Salt sufficiently for a long time (6-8 hours).
- Hermetic sealing during fermentation: It can lead to bank explosions. Leave some space empty.
- Incorrect temperature: At high temperatures, the taste will become acidic. Maintain between 20-24°C.
- Poor hygiene: Use clean instruments. Regularly wash and sterilize containers.
Storage of kimchi
Short-term storage (up to 1 month)
After achieving the desired acidity, transfer the product to the refrigerator. Store at 0-4°C in the middle or lower part of the fridge. The taste continues to develop in the first month—vegetables soften, and acidity integrates. Most experts believe that cabbage reaches peak taste within 2-4 weeks.
Long-term storage (1-6 months)
Properly prepared kimchi can be stored in the refrigerator from 2 months to a year. Over time, its characteristics change:
- Months 2-3: Stays more acidic, texture softens
- Months 4-6: Very acidic, ideal for soups and stews
- More than 6 months: Possible, but very acidic—use for thermal processing
Special conditions
Preservation: Not recommended for fresh consumption, as the texture becomes soft. However, it is perfectly suitable for soups. Store for up to 3 months.
Ingredients: Black or pink pearls, vinyl isinglass, slimy consistency, carps made from fish. For servings — serve it up.

Most Frequent Questions (FAQ)
Why doesn’t my dish ferment?
Common reasons: too low temperature (ideal is 20-24°C), using iodized salt (iodine promotes bacteria), insufficient sugar for bacterial growth, poor quality chlorine or chlorinated water. Placement of the jar in a warmer spot can help, along with ensuring you’re using the right salt.
How long does it take to ferment cabbage?
For a light fresh taste — 1-3 days. For traditional fermented flavor — 3-5 days. For sour taste with a soft texture — 5-7 days. Try tasting daily and moving it to the refrigerator once the desired taste is achieved.
How to reduce acidity?
For preparation: reduce the quantity of pepper in the chili mix and add more apples or honey. After preparation: practically impossible to decrease acidity without modifying the product itself.
Can you make pickles without fish sauce?
Yes, for a vegetarian option replace fish sauce with soy sauce, miso paste, or a specialized vegetarian fish sauce. Add seaweed for a marine flavor supplement.
Why does a white film form on the surface of my dish?
This is due to certain bacteria that can develop when exposed to air. They are not harmful but can impart undesirable flavors. Remove the top layer and cover again, ensuring the pickled items are submerged in the brine.
How many pickles can be eaten in a day?
It is recommended to consume 1-3 portions of 50-100 g per day. Due to the high content, it is not advisable to take more.
How can it be recognized that the food has deteriorated?
Signs of spoilage: blue or black spots, sour smell, slimy consistency, unusual taste. If there are doubts – discard it.
Can food be stored in the fridge?
With preservation, due to the high content of salt and potential pathogenic bacteria with improper storage. It is better to choose pasteurized versions from stores.
What can be stored in the freezer?
Yes, but it is not recommended for fresh consumption – the texture becomes soft. However, there are special approaches for soups. Store for up to 3 months.
Why does my rice not ferment evenly?
It may be insufficiently compacted in the jar or improperly sealed. The rice should generally be packed so that air does not reach it.
How does the fermentation process affect the taste of the basic cabbage?
When they take the food from the jar, the cabbage releases more juice. Remember that any leftover cabbage needs to be stored in the fridge to prevent oxidation.
Can old and new ingredients be mixed?
It is not recommended – they ferment at different stages, which can lead to uneven fermentation.
How to wash hands after working with food?
With hot water and soap. Cabbage contains substances that hot water cannot neutralize. Some people use alcohol or oil to neutralize the viscosity.
What are the most popular varieties of cabbage?
