Korean Jang (장): Gochujang, Doenjang, and Ganjang -

Many Korean dishes get their deep, savory flavor from jang (장), a family of traditional fermented sauces and pastes. The three best-known kinds are gochujang (고추장), doenjang (된장), and ganjang (간장). They have different flavors and uses, but all help season food and build the familiar taste of Korean cooking.

Jang-making is also part of Korea’s food heritage. In 2024, UNESCO inscribed the knowledge, beliefs, and practices related to jang-making in Korea on its Representative List of the Intangible Cultural Heritage of Humanity.

What Is Jang?

The word jang refers to Korean sauces and pastes made through fermentation. Gochujang, doenjang, and ganjang are the kinds visitors are most likely to encounter in Korean recipes and restaurants.

Fermentation gives these seasonings a depth that plain salt alone cannot provide. A spoonful of doenjang can add a hearty, savory flavor to soup; ganjang seasons a dish while adding salt and umami; and gochujang brings a blend of chili heat, savoriness, and mild sweetness. Cooks use them to season food, build its flavor, or serve it as a dipping sauce.

Traditional jang-making has also been a household and community practice, passed down through generations. The process and recipes vary, and today many people buy ready-made jang at grocery stores.

Gochujang (고추장): Korean Fermented Chili Paste

Gochujang is a thick, red fermented paste with a spicy, savory, and slightly sweet flavor. Recipes and products vary, but it is commonly made with red pepper powder, fermented soybean ingredients, and grains such as rice or glutinous rice.

It is used in dishes such as tteokbokki (떡볶이), bibimbap (비빔밥), and gochujang jjigae (고추장찌개). It also appears in marinades for meat and seafood. When mixed with vinegar and other seasonings, it becomes chogochujang (초고추장), a tangy dipping sauce often served with raw fish or vegetables.

Gochujang can be quite spicy, though the heat and sweetness differ by brand and recipe. If you are new to Korean food, try a small amount first and mix it into the dish gradually.

Doenjang (된장): Korean Fermented Soybean Paste

Doenjang is a thick, brown soybean paste with a strong, earthy, savory flavor. It is often compared to Japanese miso because both are fermented soybean pastes, but the ingredients, fermentation methods, and flavors can differ.

One of the best-known ways to eat doenjang is in doenjang jjigae (된장찌개), a Korean soybean paste stew often made with tofu and vegetables. Doenjang is also used in doenjang-guk (된장국), a lighter soup, and as a seasoning for vegetables and other dishes. A small amount can add a deep, savory taste to a pot of broth.

Doenjang is also one of the ingredients in ssamjang (쌈장), a thick dipping sauce commonly served with grilled meat and lettuce wraps. Ssamjang often combines doenjang and gochujang with other seasonings.

Ganjang (간장): Korean Soy Sauce

Ganjang is Korean soy sauce. Soy sauce is used in many countries, but Korean ganjang has its own varieties and culinary traditions.

Traditional Korean-style soy sauce is made by fermenting meju (메주), blocks of fermented soybeans, in salted water. In this traditional process, the liquid becomes ganjang and the remaining solids become doenjang. The two seasonings are connected through the same fermentation process.

There are different types of ganjang in Korea. Guk-ganjang (국간장), or soup soy sauce, is commonly used to season soups and namul (나물), seasoned vegetable dishes. Other soy sauces, including brewed varieties, are often used in marinades, braised dishes, and everyday cooking. The taste and saltiness vary, so Korean recipes may call for a particular kind.

Jangdokdae: The Traditional Place for Fermentation

A jangdokdae (장독대) is an area around a traditional Korean home where families kept jars of jang and other preserved foods. It might be set in a sunny, open part of the yard, with rows of jars arranged on a raised platform. The jars themselves are called jangdok (장독); many are made from onggi (옹기), a type of Korean earthenware.

The jars were used to ferment and store doenjang, ganjang, gochujang, and other foods. Onggi is valued for allowing air and moisture to pass through its walls, supporting the slow fermentation process. In the past, preserving food was especially important for keeping a supply of ingredients through the winter.

The jangdokdae was more than a storage area. It was part of the household’s food routine: jars needed to be kept clean, covered, and tended as the jang matured. Not every Korean home has a jangdokdae today, but the sight of earthenware jars remains a strong image of traditional Korean food culture.

How Far Back Does Jang Go?

The exact beginning of jang-making is unknown. The Samguk Sagi (삼국사기), a historical chronicle, records that in 683, during the Silla period, jang and si (시), another fermented soybean food, were included among the gifts sent for a royal marriage. The entry shows that these foods were valued more than 1,300 years ago, although it does not describe the exact recipes or methods used at that time.

Later records show that jang was important to ordinary people as well as the royal court. In 1018, during the Goryeo period, salt and jang were distributed to people suffering during a time of hardship. That tells us jang was not just a luxury seasoning: it was considered an important food supply.

Over generations, families developed ways to make, ferment, store, and use jang. The process connected food preparation with seasonal work, household knowledge, and shared traditions. That broader cultural practice is recognized by UNESCO, which inscribed Korea’s jang-making knowledge, beliefs, and practices in 2024.

How Jang Shapes a Korean Meal

Jang helps give different Korean dishes their distinct character. Doenjang makes stews and soups hearty and savory. Gochujang gives dishes such as tteokbokki their spicy, sweet, and savory flavor. Ganjang seasons soups, vegetables, marinades, and braised dishes.

A Korean meal may include more than one kind of jang across its dishes: a stew seasoned with doenjang, vegetables dressed with ganjang, or a spicy main dish made with gochujang. These seasonings link everyday foods to a long tradition of fermentation and home cooking.

Buying and Trying Jang

Gochujang, doenjang, and ganjang are easy to find in Korean supermarkets and online shops. Many packages include English descriptions, but the flavor and saltiness can differ between brands.

If you are trying Korean cooking for the first time, start with a familiar dish: doenjang jjigae for soybean paste, tteokbokki for gochujang, or bulgogi (불고기) for ganjang. Tasting the three in different dishes is an easy way to see how each one contributes a different flavor to Korean food.
