Tzuyu Somen
Tzuyu Somen is a refreshing Japanese summer dish featuring thin wheat noodles served cold with a savory, umami-rich dipping sauce called tsuyu. The noodles are typically made from wheat flour, while the dipping sauce is a blend of dashi (stock from bonito flakes and kelp), soy sauce, and mirin, often accompanied by toppings like grated ginger, scallions, or shiso leaves. It's a staple in Japan, especially during hot months, and is also popular in other East Asian countries with local variations.
