Doenjang-jjigae

The origin of doenjang, which is used as the primary ingredient of doenjang-jjigae, dates back to as early as the Korean Three Kingdoms period.[4] Korea was largely agricultural, with vast farmlands but unstable, insufficient sources of meat, especially during winter. In the search for easily prepared relief substitutes of sources of protein, Korean farmers began cultivating jang (sauce/paste) from various plants and seeds.[5] Doenjang was first produced during this period through the fermentation of soybeans in the form of meju. Fermented soybean paste is a rich source of isoflavone,[6] which helps in preventing cardiovascular diseases and supplies daily nutrients to the body.[7]

The first official record of the use of doenjang is written in the Samguk Sagi, the historical records of the Three Kingdoms era registered by government officials and scholars. In the Samguk Sagi, it is recorded that doenjang and other varieties of jang were served at the wedding ceremony of King Sinmun of Silla in 683 CE.

The earliest form of doenjang jjigae is mainly connected to ‘curled mallow soup’, which is mentioned in the Jeungbo sallim gyeongje, a record of Korean agriculture by physician Yu Jung-Rim during the rule of King Youngjo (1724 – 1776). Curled mallow soup is a traditional Korean soup-type dish where mallow leaves and other vegetables are boiled in a doenjang-filled broth, and served as a soup complementary with rice. Since this period, various provinces and regions around the Korean peninsula began to develop their own unique recipes of doenjang-jjigae, and most varieties of these soybean paste stew are still maintained.

Factory-produced doenjang

There are many variations and subtle differences in the ingredients used in cooking doenjang-jjigae in accordance to its originating province[8]. Primary and typical ingredients commonly found doenjang-jjigae include doenjang (fermented soybean paste), dried anchovies, white radish, Korean chili pepper, minced garlic, water, onions, green onions, potato, zucchini, and medium-firm tofu.

Doenjang-jjigae was traditionally cooked with homemade soybean paste, which was commonly prepared in most households, similar to the preparation of kimchi. Industrialization brought a nationwide shift to using factory-made doenjang-jjigae.

Many other ingredients can be added to doenjang-jjigae for a heartier meal, especially meat or seafood. These secondary ingredients significantly change the taste of the broth and stew,[9] so it is usually referred to by a slightly different name according to the ingredient used. The most common seafood ingredients added to doenjang-jjigae include prawns or small clams, and beef is the most popular and commonly found meat ingredient.

Korean barbecue with supplementary banchans

The preparation stage of doenjang-jjiage is largely divided into two stages: the initial boiling of the broth, and the following addition of ingredients. The first step of cooking soybean paste stew is making the base broth. The base broth is made by adding dried anchovies and white radish to the pot of water and bringing to a boil for around 15 minutes. Then, the key ingredient doenjang, along with chilli pepper, is stirred into the broth and mixed carefully. The broth is set to boil for a further 10 to 20 minutes before filtering the anchovies out of the broth. Next, ingredients are added into the broth in the general order of potato and zucchini first for enough time for them to soften, then onions, green onions and tofu, and finishing with the addition of minced garlic for more pungent flavor.

In contrast to doenjang-guk, doenjang-jjigae is served at the center of the dining table, mainly as a sharing dish between two or more people. Similarly to other jjigae-type dishes, doenjang-jjigae is served alongside steamed rice, and other banchans (side dishes) consisting of meat or vegetables. Doenjang-jjigae is commonly served as an accompanying stew when ordering meat at Korean barbeque.

Doenjang contains isoflavone, which helps prevent diseases such as cardiovascular disease or osteoporosis, and lecithin, which helps improve brain function, so it is effective not only for growing children, but also for adults and the elderly. In addition, doenjang is rich in dietary fiber, which is beneficial for digestive system functions.[10]

Naengi (horseradish) doenjang-jjigae

Multiple varieties of doenjang-jjigae can be found in Korean cuisine, different in taste, presentation, regionality, and steps of preparation and consumption. These varieties are usually distinguished by their unique main ingredient, which the dish itself is usually named after, with doenjang-jjigae following it.

• Kkot-gae (swimming crab). The carapace and legs of swimming crabs are added in the process of making the broth. The crab adds sweetness and deep taste to the stew.
• Cha-dol-bae-gi (beef brisket). Fried beef brisket in oil is added to the broth and boiled with the rest of the normal ingredients of doenjang-jjigae. Beef brisket doenjang-jjigae is usually served at Korean barbecue restaurants as a complementary dish to the meat.
• Bajirak (Manila clam). Clams are de-gritted and prepared, then added into a cooked doenjang-jjigae for deeper taste of savory.
• 

  Gang-doenjang-jjigae
  sundubu (curdled soft tofu). Medium tofu is usually chosen over soft tofu in cooking stews since soft tofu is very delicate and de-solidifies easily, but soft tofu can be used in cooking doenjang-jjigae for a softer stew for children.
• Dallae (Korean wild chives). Dallae is added into the broth of doenjang-jjigae just before bringing to boil. The chives releases a pungent and mildly herbal taste into the stew.
• Naengi (horseradish). The leafy roots of horseradish a reblanched in hot water, then added to a cooked doenjang-jjigae at the end for spicy flavor. Horseradish is often consumed for its richness in protein, calcium, and iron nutrients.[11]
• Gang-doenjang. Vegetable ingredients are first stir-fried with doenjang and gochujang; less water than in the usual doenjang-jjigae recipe is added and brought to a boil until the stew has a thick consistency.
