It is a comforting, rustic meal that showcases the beauty of simple ingredients transformed by hand into a masterpiece of texture.

🥗 Ingredients

For the Noodle Dough

  • 3 cups All-purpose flour (plus extra for dusting)
  • 3/4 cup Water (room temperature)
  • 1 tablespoon Vegetable oil
  • 1/2 teaspoon Fine sea salt
  • 1/4 cup Cornstarch (for dusting and folding)

For the Anchovy Broth

  • 10 cups Water
  • 15 pieces Large dried anchovies (heads and guts removed)
  • 1 piece Dried kelp (Dashima) (approx. 4x4 inches)
  • 3 pieces Dried shiitake mushrooms
  • 2 tablespoons Fish sauce (or soup soy sauce)

Vegetables and Toppings

  • 1 medium Potato (peeled and sliced into matchsticks)
  • 1/2 medium Zucchini (julienned)
  • 4 cloves Garlic (finely minced)
  • 2 stalks Scallions (sliced diagonally)
  • 1 sheet Toasted seaweed (Gim) (shredded)
  • 1 teaspoon Toasted sesame seeds

👨‍🍳 Instructions

  1. 1

    In a large mixing bowl, combine the flour, salt, vegetable oil, and 3/4 cup of water. Stir with a wooden spoon until a shaggy dough forms.

  2. 2

    Knead the dough by hand for about 10-15 minutes. It should be quite firm and smooth. If it's too dry, add water one tablespoon at a time. Wrap in plastic and let it rest for 30 minutes at room temperature to relax the gluten.

  3. 3

    While the dough rests, prepare the broth. Place 10 cups of water, dried anchovies, kelp, and shiitake mushrooms in a large pot. Bring to a boil over medium-high heat.

  4. 4

    Once boiling, remove the kelp. Reduce heat to medium-low and simmer for another 20 minutes to extract the full flavor of the anchovies and mushrooms.

  5. 5

    Strain the broth through a fine-mesh sieve, discarding the solids. Return the clear broth to the pot and stir in the fish sauce.

  6. 6

    On a large, lightly floured surface, roll out the rested dough with a rolling pin. Aim for a thickness of about 1/8 inch (3mm). Make sure to keep the surface floured to prevent sticking.

  7. 7

    Dust the top of the rolled dough generously with cornstarch. Fold the dough over itself 3 or 4 times to create a flat, multi-layered log.

  8. 8

    Using a sharp knife, cut the dough into thin strips (about 1/8 to 1/4 inch wide). Toss the cut noodles gently with your hands to unfurl them, shaking off excess starch.

  9. 9

    Bring the broth back to a rolling boil. Add the potato matchsticks and cook for 3 minutes until they begin to soften.

  10. 10

    Add the handmade noodles to the boiling broth. Stir gently with chopsticks or a fork immediately to ensure the noodles do not clump together.

  11. 11

    Add the julienned zucchini and minced garlic. Let everything boil for 5-7 minutes. The noodles are done when they look translucent and have a chewy 'al dente' texture.

  12. 12

    Taste the soup and add salt if necessary. Stir in the sliced scallions and turn off the heat.

  13. 13

    Ladle the soup and noodles into deep bowls. Garnish with shredded seaweed and toasted sesame seeds. Serve immediately while piping hot.

💡 Chef's Tips

Resting the dough is non-negotiable; it ensures the noodles are chewy rather than tough. Use cornstarch instead of flour for the final dusting before cutting; it prevents the broth from becoming overly gummy. Always remove the black innards (guts) of the dried anchovies to prevent the broth from tasting bitter. If you want a clearer broth, you can boil the noodles separately in water for 2 minutes before adding them to the main soup pot. For a spicy kick, serve with a side of 'Dadaegi' (Korean chili paste seasoning).

🍽️ Serving Suggestions

Serve with fresh, unfermented Kimchi (Geotjeori) for a bright, crunchy contrast. A side of Korean dumplings (Mandu) makes this a hearty, full-course meal. Pair with a chilled glass of roasted barley tea (Boricha) to cleanse the palate. Add a few Manila clams or shrimp during the last 5 minutes of cooking for a seafood version. Provide a small dish of soy sauce mixed with vinegar and chili flakes for dipping the noodles.
