Zaru Udon

Combine soy sauce, mirin, and dashi in a pot. Warm gently, adjust seasoning, then let cool and refrigerate.

Bring water to a boil and cook the udon noodles until tender (about 8–10 minutes for dried noodles).

Drain the noodles and rinse under cold water or place in ice water to stop cooking and improve texture.

Arrange noodles on a tray or plate, top with shredded nori, and serve with dipping sauce, wasabi, and green onions.

Dip the noodles into the sauce before eating.
