Korean Jang — Gochujang, Doenjang & Ganjang-Based Pastes

What it is

The foundational fermented seasonings of Korean cooking, collectively jang: gochujang (chili paste), doenjang (soybean paste), and ganjang (soy sauce) — plus their compound derivatives like yangnyeom (seasoning) bases and gochujang-based sauces. Together they form the umami-and-heat backbone of the cuisine.

How it's made

• Ganjang (soy sauce): brewed from fermented soybean blocks (meju) and brine; traditional hansik-ganjang is the liquid drawn off doenjang fermentation, while modern brewed and blended soy sauces dominate everyday use.
• Doenjang: the soybean solids left from the meju/brine ferment, aged into a thick, funky paste — Korea's deeply savory miso-cousin.
• Gochujang: a long-fermented paste of gochugaru (Korean chili powder), glutinous rice, fermented soybean powder (meju garu), barley malt, and salt — sweet-spicy, thick, and glossy.

Flavor profile

• Ganjang: salty, savory, brewed-umami; traditional versions are funkier and lighter-colored than Japanese soy.
• Doenjang: deep, funky, salty-savory, earthy — more rustic and pungent than Japanese miso.
• Gochujang: sweet, spicy, savory, and slightly fermented-tangy, with a thick, sticky body.

Culinary uses

• Ganjang seasons soups, jang-jorim braises, banchan, and dipping sauces.
• Doenjang anchors doenjang-jjigae (stew), ssamjang, and vegetable seasonings (namul).
• Gochujang drives tteokbokki, bibimbap sauce, jeyuk bokkeum (spicy pork), marinades, and yangnyeom fried-chicken glaze.
• How to use: doenjang and gochujang are typically cooked into stews and sauces (they mellow and deepen with heat); ganjang seasons throughout; gochujang also finishes dishes as a glaze.

Regional variations

Traditional regional and household jang (often homemade in large earthenware onggi jars on the jangdokdae terrace) vary widely in funk, salt, and aging. Sunchang county is famous for gochujang. Temple cuisine and provincial styles tune the jang differently.

Cultural & historical context

Jang is the soul of Korean cuisine — its fermentation is a centuries-old craft once central to every household, traditionally made communally by women each winter and aged for years. The jangdokdae (the terrace of fermentation jars) is an iconic image of Korean domestic life, and jang-making (jang담그기 / jang-damgeugi) was inscribed by UNESCO as Intangible Cultural Heritage in 2024.

Sourcing notes Commercial gochujang, doenjang, and ganjang (CJ, Sempio, Chung Jung One) are excellent and standard even in Korean homes. Artisanal, long-aged jang from traditional makers is a notable step up. Gochujang freshness matters for color and flavor.
