Korean

Korean cooking is built around fermentation, rice, banchan, broth, grilling, and a particular kind of balance: bold but harmonized. Fermentation is central, but it is not the whole story.

Flavor logic

The backbone is the jang: fermented pastes and sauces. Gochujang (fermented chile paste; sweet-savory heat with deep funk), doenjang (fermented soybean paste; earthy and pungent, related to but not the same as miso), and ganjang (soy sauce). These bring umami and funk that nothing else replicates. Around them, Korean food balances spicy, savory, sweet, sour, bitter, and the prized gamchilmat, a satisfying moreish savoriness. Garlic -- a lot of it -- sesame (oil and seeds), scallion, ginger, gochugaru (chile flakes), dried anchovy/kelp broths, jeotgal/fish sauce, and kimchi all matter. A meal is built around rice with an array of banchan, so balance is across the table: fermented, fresh, spicy, mild, rich, and clean dishes playing off each other. Kimchi is both a side and an ingredient (kimchi jjigae, kimchi fried rice).

Core techniques

Fermentation is foundational, but be precise: kimchi and jang are fermented ingredients, not always literally "living" by the time they are cooked, pasteurized, or commercially stabilized. Marinating and grilling (gui): sweet-savory-garlicky marinades for bulgogi and galbi, then high-heat grilling for char. Soups and stews need distinctions: guk is often a lighter soup and may be individually served; jjigae is thicker, stronger, and often shared bubbling-hot; tang, jeongol, and jjim have their own logic. Many are built on anchovy-kelp, beef, seafood, or rice-rinse broths, not just doenjang or gochujang. Other everyday techniques: namul seasoned vegetables, muchim dressed salads, jeon pancakes, jorim braises, bokkeum stir-fries, jjim steamed/braised dishes, noodles, porridges, rice cakes, and ssam wrapping.

Pantry backbone

Gochujang, doenjang, ganjang/soy sauce, gochugaru (coarse Korean chile flakes, not interchangeable with cayenne or generic chili powder), toasted sesame oil and seeds, lots of garlic, scallion, ginger, rice, kimchi, dried anchovies, kelp/dashima, fish sauce/aekjeot or jeotgal, Asian pear or apple for marinades, rice syrup/sugar/honey/maesil-cheong, and sometimes cooking wine or mirin. Gochujang is easier to find now, but ask about doenjang, gochugaru, kimchi, toasted sesame oil, and broth ingredients; without them the flavor gets generic fast.

Common outsider mistakes

Generic chili powder won't behave like gochugaru; the flakes, fruitiness, and texture matter. Gochujang isn't just heat either: it's sweet, savory, fermented, and usually needs balancing rather than being smeared on neat. Garlic and sesame are not timid accents here. If doenjang, kimchi, anchovy-kelp stock, or jeotgal disappear, the fermented and marine depth goes with them, and a soy-sugar sauce won't replace it. Also keep the table in mind: rice and banchan are structure, not optional decoration. Korean food was not always red-chile hot; chiles arrived later, so don't make heat the only story.
