How to prepare

1
Combine the soy sauce, mirin, and dashi stock in a small saucepan. Bring to a gentle simmer over medium heat, then simmer for 2 minutes to round the mirin and concentrate the flavor. Transfer to a bowl and chill while the noodles cook.
2
Bring a large pot of unsalted water to a full boil. Add the soba and cook according to the package timing, usually 4 to 6 minutes, stirring once or twice, until tender but still slightly firm at the center.
3
Drain the noodles immediately and rinse them under cold running water, gently rubbing the strands between your fingers until the water runs clear. Drain thoroughly, then toss with the ice for 30 seconds and drain again.

Divide the cold noodles between two serving platters. Top each portion with the shredded nori, and place the sliced scallions and wasabi alongside. Pour the chilled dipping sauce into two small bowls.

5
Serve immediately. Dip a small bundle of noodles into the sauce just before eating, adding scallions and a little wasabi to each bite so the noodles remain cold and the sauce stays balanced.

Why this recipe works

Rinsing and chilling the soba stops cooking and removes excess starch, while the concentrated dashi-soy dipping sauce provides enough savory depth to season each cool, clean bite without making the noodles soggy.

Storage and reheating

How to store it

Store the rinsed noodles and dipping sauce separately in airtight containers for up to 1 day. Keep garnishes separate and refrigerate promptly.

How to reheat it

Do not reheat. Refresh refrigerated noodles briefly under cold water, drain well, and serve chilled.
