It looks like udon, but it isn’t. What’s the secret behind the deliciousness of Korea’s handmade noodle dish, “Kalguksu”?

Did you know that Korea has a noodle dish that looks like udon but is different from udon?
It’s called “Kalguksu (칼국수).”

Handmade noodles cut with a knife are simmered in a soup made with flavorful clam or chicken broth,
giving the soup just the right amount of thickness so it clings deliciously to the noodles.

This time, we’ll introduce all the irresistible appeal of Kalguksu, a Korean comfort food you’ll definitely want to try on your trip to Korea.

🍜 What Is Kalguksu? The Origin of Its Name

In Korean, “Kalguksu” means:

• ・　Kal (칼) = knife

• ・　Guksu (국수) = noodles
  　　In other words, it means “noodles cut with a knife.”

Because the dough is made by kneading wheat flour, rolling it out thinly, and roughly cutting it with a knife,
it tends to have a pleasantly chewy texture and just the right amount of firmness.
In Korea, it is beloved as a home-cooked dish, and many people say it reminds them of “the taste of home.”

🥢 The “Decisive Difference” Between Udon and Kalguksu

Although it looks similar to udon, the preparation method is quite different.

• ・　Udon: The noodles are boiled in a separate pot before being added to the broth
  　　　→ The soup tends to have a relatively light, smooth consistency

• ・　Kalguksu: The noodles are cooked directly in the soup
  　　　→ The starch from the noodles dissolves into the soup, giving it a thick, silky texture

• 
  

This “thickness” clings beautifully to the noodles, making it especially enjoyable to savor piping hot until the very last bite.

🌊 A Wide Variety of Broths! The Fun of Choosing Your Favorite

One of kalguksu’s greatest charms is the wide variety of broths.
Each restaurant has its own unique style, making it fun to compare different versions.
