Gochujang, Gochugaru, Doenjang: A Guide to the Korean Pantry

Open any Korean recipe and it assumes three things are already in your kitchen: gochujang, gochugaru, and doenjang. Two of those names start the same way and mean different things, the third gets described as "Korean miso" by people who have never tasted them side by side, and substituting any of them produces a dish that is recognizably wrong. This is the fifteen minutes of reading that makes the rest of Korean cooking straightforward.

Gochugaru is the pepper

Gochugaru is Korean chili powder: red peppers, sun-dried, deseeded, and ground. That is the whole ingredient. No fermentation, no additives, nothing else in the bag.

What matters when you buy it is the grind, because Korean cooking uses two and they are not interchangeable:

• Coarse grind. Flaky, closer to crushed red pepper. This is the kimchi grind. The flakes stay visible in the paste and disperse slowly.
• Fine grind. Closer to a true powder. Used in sauces, stews, and pastes where you want the colour and heat to dissolve in.

Gochugaru is not very hot by international standards, which surprises people. It sits well below cayenne, and much of what it contributes is a fruity, faintly smoky sweetness and a deep red colour rather than raw burn. Substituting cayenne makes a dish hotter and flatter at the same time, which is the worst of both trades.

Gochujang is the paste

Gochujang is fermented, and that is the entire difference. It starts with gochugaru, then adds fermented soybean powder, a starch (traditionally glutinous rice), salt, and usually a malted sweetener, and then it ferments, historically in an earthenware jar left outdoors through the seasons.

The result is thick, deep red, and does four things at once: sweet, salty, savoury, and hot, in that rough order of prominence. It is not "spicy paste." It is a seasoning with the complexity of a soy sauce and the heat of a mild chili, and it goes into bibimbap sauce, tteokbokki, stews, and marinades.

The practical point: you cannot substitute gochugaru for gochujang or the reverse. One is a dry spice, the other is a fermented wet seasoning carrying salt and sugar. Swapping them changes the dish's salt level, its liquid, and its sweetness all at once.

Doenjang is the soybean one

Doenjang is fermented soybean paste, and calling it Korean miso is close enough to be useful and wrong enough to be worth correcting. Both are fermented soybeans. The processes differ, and so do the results.

Traditional doenjang starts with meju, blocks of cooked, mashed soybeans left to dry and ferment with wild ambient cultures rather than an introduced mould. The meju then goes into brine. What is drawn off the top becomes ganjang, Korean soy sauce. What remains behind becomes doenjang. The two are made together, which is why traditional Korean kitchens treated them as one process rather than two products.

The flavour runs funkier, saltier, and more assertive than most Japanese miso, and it is the backbone of doenjang jjigae, the everyday stew that anchors a Korean home table.

Ssamjang, the fourth one nobody explains

If you have eaten Korean barbecue, you have used ssamjang: the thick, slightly sweet paste that goes onto the lettuce wrap. It is not a separate fermented product. It is a mix, built from doenjang and gochujang with sesame oil, garlic, and usually chopped scallion and a little sugar.

You can buy it in a tub, and you can also make it from the two pastes above the moment you own both, which is a decent argument for buying them.

Why all of this is called jang

Gochujang, doenjang, and ganjang share the same suffix because they are the same family: jang, Korea's fermented seasonings. It is not a marketing category or a loose grouping. In December 2024, UNESCO inscribed jang-making on its Representative List of the Intangible Cultural Heritage of Humanity, recognizing the knowledge and communal practice behind it, and noting that the amino acids fermentation produces supply a nutritional balance the rice-based Korean diet would otherwise lack.

That is a useful frame for a beginner. These are not condiments added at the end. They are the base layer the cuisine is built on, which is why so many recipes treat owning them as a given.

What to buy first

• Gochugaru, coarse grind. The single most useful bag, and the one hardest to fake with a substitute.
• Gochujang, a standard tub. Heat levels are usually printed on Korean packaging as a numbered scale; the middle of the range is a safe start.
• Doenjang, the plainest tub on the shelf. Check that soybeans and salt lead the ingredient list.

Buy them at a Korean grocer rather than a general supermarket if you can. The turnover is faster, the range is wider, and gochugaru in particular loses its colour and aroma sitting on a shelf.

The short version

Gochugaru is dried ground chili. Gochujang is a fermented paste that contains gochugaru along with soybean, starch, and salt. Doenjang is fermented soybean paste and the sibling of Korean soy sauce. Ssamjang is the first two mixed together. Learn those four and most Korean recipes stop needing translation.
