Tsuyu / dashi brothessentialDashi, soy sauce, and mirin; served cold for dipping or hot as broth
Wheat flouroptionalOften added for elasticity; absent in pure juwari soba
Scallion, wasabi, norioptionalStandard condiments, especially for chilled soba
Technique
- Milling and kneading buckwheat dough
- Low-gluten buckwheat is fragile, so careful hydration and kneading are needed to form workable dough
- Hand-cutting thin even noodles
- Uniform thin strands cook evenly and give the proper texture
- Rinsing chilled noodles in cold water
- Stops cooking and tightens the noodles for the firm bite of zaru soba
- Building dashi-based tsuyu
- The umami broth/dip is what carries the dish; balance defines hot vs cold service
