Kalguksu (칼국수) literally translates to “knife noodles” or simply “knife-cut noodles” in English.

Kalguksu is typically served with broth or soup.

There are various types of guksu, such as dak kalguksu (chicken noodle soup), seafood kalguksu, and many others. Making a note to myself to try making these different varieties of kalguksu!

How to Make Kalguksu?

Kalguksu is made from a mixture of wheat flour, salt, oil, and water. The key to making a good kalguksu lies in finding the right ratio of wheat flour to water.

How long can I store Kalguksu?

I strongly advise against keeping Kalguksu overnight, as it is best enjoyed fresh and not recommended for prolonged storage.

They have a tendency to become soft and sticky.

Kalguksu is at its best when served on the same day it is prepared and should be served immediately for the optimal taste and texture.
