The usual shape of Ise udon is spare: thick soft noodles, a little tamari-based sauce, and few toppings beyond chopped green onion. The sauce is built around tamari soy sauce and bonito dashi, while some shops adjust it with other dashi, mirin, or their own methods. Its dark color can look strong, yet the described taste leans toward umami, sweetness, and a mellow finish. The noodles matter because their softness and thickness help them catch the sauce, so each bite carries tamari, dashi, and green onion on the noodle surface.
