  • 8 ounces dried soba (buckwheat noodles) half 16 ounce package

Cold Soba Dipping Sauce

  • 1 cup dashi stock For the HonDashi stock brand, add 1 teaspoon seasoning to 1 cup of water.  Follow instructions on how to make the dashi broth based on the brand you get.

Optional toppings

  • scallions, thinly sliced

  • Rinse the cooked noodles in a strainer under cold water.
  • Submerge the noodles in a big bowl with cold water and ice. Set aside until ready to serve.
  • Make the dipping sauce. Add dashi stock, mirin and soy sauce into a small sauce pan and take it to a boil on medium heat, about 5 minutes.
  • Turn off the heat, let the sauce cool to room temperature or place it in the refrigerator for a quicker cool down.
  • To serve, portion out the noodles and place them on a Zaru mat (if you don’t have one, make sure to drain the noodles really well with a strainer). Portion the sauce in a small bowl and serve on the side. 
  • To eat, add optional condiments to the dipping sauce. Take some noodles and dip it into the sauce and enjoy it with a nice slurp!
