A deep-red fermented paste made from red chili powder, glutinous rice, fermented soybeans, and salt. It is the backbone of Korean cooking — adding heat, sweetness, and deep umami to everything from stews to marinades. Fermented for months or even years, it develops a complexity that no fresh chili can replicate.

Korean fermented soybean paste — the counterpart to Japanese miso but with a stronger, more pungent flavor. Made by fermenting whole soybeans for months in large clay pots. It is the defining ingredient in doenjang jjigae and is also used as a dipping sauce (ssamjang when mixed with gochujang).

Korean soy sauce comes in two main varieties: "joseon ganjang" (a light, more savory traditional style brewed from fermented soybeans) and "yangjo ganjang" (a Japanese-style brewed soy sauce). Used in virtually every Korean dish for seasoning, marinades, and dipping sauces.

Toasted sesame oil is the aromatic finishing oil of Korean cooking. A few drops added at the end of cooking transforms a dish. It is made by pressing toasted sesame seeds and has a deep, nutty fragrance completely different from untoasted varieties. Always use toasted (dark) sesame oil for Korean recipes.

Korean fish sauce (aekjeot) is made by fermenting salted fish for months or years. It adds a deep, savory umami base to kimchi, soups, and stews. Korean anchovy fish sauce (myeolchi aekjeot) is the most common variety — slightly lighter in color and flavor than Southeast Asian fish sauces.

Korean red pepper flakes — coarsely ground sun-dried red chilis. This is the ingredient that gives kimchi its iconic red color and signature heat. Gochugaru is less spicy than cayenne and has a slightly smoky, fruity sweetness. It comes in two grinds: fine (for gochujang and sauces) and coarse (for kimchi and marinades).

Large, serrated leaves with a unique flavor that is somewhere between basil, mint, and anise. Perilla leaves (kkaennip) are eaten fresh as ssam wraps, pickled as banchan, or added to soups and stews. They are different from Japanese shiso — more robust in flavor.

The national dish and cultural icon of Korea. Kimchi is lacto-fermented napa cabbage seasoned with gochugaru, garlic, ginger, and salted shrimp or fish sauce. It is both a banchan (side dish) and a key cooking ingredient. Well-fermented "old" kimchi (묵은지) is preferred for cooking, while fresh kimchi is better as a side dish.

The most important vegetable in Korean cooking and the primary ingredient in baechu kimchi (the most common type). Napa cabbage has tender, sweet leaves with a mild flavor. It is salted to draw out moisture before being coated in kimchi paste.

Dried kelp used to make Korean stock (yuksu). Dasima is simmered briefly — not boiled — to extract its natural glutamates for a clean, savory broth. It is the backbone of light soups and provides a subtle oceanic depth without an overpowering fishy taste.

Korean sweet potato glass noodles — thick, chewy noodles made from sweet potato starch. They are the star ingredient of japchae. Unlike Chinese glass noodles made from mung bean, dangmyeon have a unique springy, bouncy texture that holds up well to stir-frying and absorbs sauce beautifully.

Korean rice cakes come in dozens of shapes and varieties. For tteokbokki, cylindrical garaetteok (tube-shaped) are used. They are made from pounded or ground glutinous rice, giving them a soft, chewy, and slightly sticky texture. Fresh tteok is best but dried or frozen works well too.

Small, dried anchovies used to make the base stock in most Korean soups and stews. Simmered with dasima, they create a rich, complex broth with deep savory flavor. The larger the anchovy, the stronger and more intense the flavor. Heads and guts are sometimes removed for a cleaner taste.

Makgeolli is Korea's oldest alcoholic drink — a lightly sparkling, milky-white rice wine with a gentle sweetness and slight tartness. It is also used in cooking to tenderize meat and add depth to pancake batter. At around 6-8% alcohol, it is much lighter than soju.

A sweet rice cooking wine used to add a gentle sweetness and glossy sheen to dishes. Korean mirim is slightly less sweet than Japanese mirin. It also helps eliminate fishy or gamey odors in meat and seafood dishes.
