Zaru Soba (Cold Buckwheat Noodles with Dipping Sauce)

Cold buckwheat noodles on bamboo with a small cup of intensely savory tsuyu dipping sauce. The simplest expression of soba flavor. Dip the bottom third of the noodles only — you want a gradient of flavor, not full immersion.

Soba loses texture fast. Serve immediately after rinsing. Do not let it sit.

What You Need

  • 200g dried soba noodles

Tsuyu dipping sauce:

  • 240ml dashi
  • 3 tbsp soy sauce
  • 2 tbsp mirin (briefly heated and cooled to burn off alcohol)

Garnish: sliced scallion, wasabi, toasted nori strips

How to Make It

Make tsuyu: Combine dashi, soy sauce, and cooled mirin. Chill completely. (Make ahead — keeps refrigerated 5 days.)

Cook soba: Bring 2L water to a vigorous boil. No salt. Add soba. Cook 5-6 minutes, testing frequently. Drain.

Rinse: Rinse under cold running water, rubbing gently with your hands to remove surface starch. Shake off excess water.

Serve: Arrange noodles on bamboo or a plate. Pour tsuyu into individual small cups.

Eating: Dip the bottom third of each chopstick-bundle into tsuyu. Eat. Add scallion and wasabi to the tsuyu (not the noodles).

Sobayu: Add the starchy cooking water to remaining tsuyu at the end. Drink as broth.
