Jjigae is a Korean stew. There are many varieties; it is typically made with meat, seafood or vegetables in a broth seasoned with gochujang, doenjang, ganjang or saeujeot. Jjigae is usually served in a communal dish, boiling hot.
Guk, also sometimes known as tang, is a class of soup-like dishes in Korean cuisine. Guk and tang are commonly grouped together and regarded as the same type of dish, although tang can sometimes be less watery than guk. It is one of the most basic components in a Korean meal, along with bap (rice), and banchan (side dishes).
A Korean meal almost always includes either a jjigae or a guk.
