  • Serves

    serves 2 as an appetizer

  • Cook

    1 day 30 minutes



  • 2 strips (2 inches each) kombu (3 g)
  • ½ cup (5 g) katsuobushi (dried bonito flakes)
  • 3 medium garlic cloves, coarsely chopped (1 Tbsp.)
  • ½ medium Asian pear, seeded and cored (2½ oz.)
  • ½ cup thinly sliced shallots (1½ oz.)
  • ½ cup gochujang (Korean red chile paste)
  • 2 Tbsp. toasted sesame oil
  • 1 Tbsp. plus 1½ tsp. sugar
  • 1½ tsp. soy sauce
  • 1½ tsp. rice vinegar
  • 3 oz. somyeon (thin Korean wheat flour noodles), cooked according to package instructions and rinsed in cold water
  • ¼ English cucumber, cut into thin matchsticks (1/3 cup)
  • 2 Tbsp. thinly sliced store-bought or homemade kimchi
  • 1 soft-boiled egg, halved


Step 1

In a small pot, add the kombu and ⅔ cup cold water. Bring to a boil, then stir in the katsuobushi and immediately turn off the heat. Set the dashi stock aside for 15 minutes.

Step 2

Set a fine-mesh strainer over a liquid-measuring cup. Strain the dashi, pressing on the solids with the back of a spoon. Measure ½ cup dashi and reserve any remaining for another use.

Step 3

Purée the dashi, garlic, pear, and shallots in a blender until smooth. Add the gochujang, sesame oil, sugar, soy sauce, and rice vinegar, and pulse until combined. Transfer the sauce to an airtight container and refrigerate at least 2 days before using.

Step 4

In a medium bowl, add the noodles and 3 tablespoons sauce, or more to taste. Reserve remaining sauce for another use. Using tongs or a gloved hand, toss well to coat. Transfer to a serving bowl and top with the cucumber, kimchi, and egg. Serve immediately.
