Ingredients
For the Dipping Sauce (Tsuyu)
- 4 g dried kombu seaweed
- 10 g bonito flakes
- 1 cup cold water
- 1/2 cup soy sauce
- 1/4 cup mirin
- 2 tbsp sake
- 1 tsp granulated sugar
For the Noodles and Garnishes
- 14 oz (400 g) dried soba noodles
- 1 sheet toasted nori, thinly sliced
- 2 scallions, finely chopped
- 1 tsp prepared wasabi paste
- 1/4 cup grated daikon radish
Directions
- Make the dashi: soak kombu in 1 cup cold water for 30 minutes, then heat gently over medium. Just before boiling, remove the kombu and add the bonito flakes. Steep 5 minutes, then strain through a fine sieve.
- In a small saucepan, combine the dashi, soy sauce, mirin, sake, and sugar. Bring to a gentle simmer for 2 minutes until the sugar dissolves, then cool to room temperature and chill thoroughly in the refrigerator.
- Bring a large pot of unsalted water to a rolling boil. Add the soba noodles and stir immediately so they do not stick together.
- Cook the noodles according to package directions, usually 4 to 5 minutes, until tender but still slightly firm to the bite.
- Drain the noodles in a colander and immediately rinse under cold running water, rubbing gently between your hands to wash away the surface starch. Continue rinsing until the noodles feel cool and silky.
- Drain the noodles very well, shaking off excess water, and divide into four neat mounds.
- Arrange the noodles on a bamboo mat, platter, or individual plates. Pile the sliced nori and chopped scallions into small dishes, and place grated daikon and wasabi alongside.
- Pour the chilled dipping sauce into four small individual bowls.
- Serve the noodles with the dipping sauce and garnishes at the table. To eat, dip a small bundle of noodles into the sauce (add wasabi and daikon to taste) and slurp audibly, which is considered proper etiquette and enhances the flavor.
Cook’s Notes
- Choose 100 percent buckwheat (juwari) soba for the most authentic nutty flavor, though a wheat-blend soba is more forgiving to cook and easier to handle.
- The dipping sauce can be prepared up to 5 days ahead and kept refrigerated in a sealed container; it also freezes well for up to a month.
- Rinse the noodles thoroughly in cold running water to wash off the surface starch, which is essential for the right firm, springy texture and clean flavor.
- If the dipping sauce tastes too strong, dilute it with extra dashi or cold water until it reaches your preferred salt level.
- Serve the noodles on a traditional bamboo zaru mat if you have one, since the gaps let excess water drain away and help keep the noodles from getting soggy.
