What Is Udon Broth Made Of?
Udon broth is typically made from a combination of dashi (a broth made from dried kelp and dried fish flakes), soy sauce, and mirin (a sweet rice wine). Other common ingredients include sake, ginger, and green onions. The broth is typically simmered for a few hours to extract the flavors from the ingredients and is then strained before being served with udon noodles and various toppings.
