Kalguksu is a very yummy noodle soup from Korea that is made with thin, flat noodles that are kind of like spaghetti.
The soup is usually made with a clear broth that has been simmered with things like chicken, beef, or anchovies to make it very flavorful.
The noodles are made by mixing flour and water until it forms a dough, which is then rolled out and cut into thin, flat strips that look a bit like fettuccine.
The broth and noodles are then combined in a bowl and usually served with things like vegetables or pieces of meat on top.
It's a really popular dish in Korea, especially during the colder months when people want something warm and comforting to eat. It's kind of like chicken noodle soup, but with a Korean twist!
