- 3 cup water
- one 1/3-ounce dashi packet
- 1/4 cup mirin
- 1/4 cup soy sauce
- pinch of salt
- 14 ounce dried soba
- 2 scallions, green and white parts, chopped finely
- wasabi paste, for serving
- finely shredded nori sheets, for serving
- In a medium-sized saucepan, combine the water and dashi packet. Cover with a lid and cook over medium-high heat. Once it reaches a boil, reduce the heat to medium-low and simmer for 5 minutes. Discard the packet. Pour out 1 ½ cups of the stock and reserve for another use.
- Add the mirin, soy sauce, and salt to the remaining stock and bring to a boil. Add more dashi stock if the sauce is too thick. Remove from the heat and let cool. (The dipping sauce is supposed to be a little salty because you will be "dipping" the soba noodles instead of soaking them to eat. You can always dilute it later if needed.)
- Bring a large pot of water to a boil over high heat. Do not salt the water. Add the dried soba in a circular motion, separating the noodles from each other. Boil according to the package directions. Stir occasionally so they don't stick to each other. Do not overcook.
- Drain the noodles in a colander and wash the noodles in a cold running water — this is very important and key to great tasting soba noodles.
- Put the scallions and wasabi on a small plate. Serve the soba noodles on a tray or dish. Top with finely shredded nori sheets right before serving.
