What is tsuyu?

Tsuyu, also known as Japanese soba dipping sauce, is a flavorful condiment made primarily from dashi (a Japanese soup stock), soy sauce, and mirin (sweet rice wine). It is commonly served with cold soba noodles, allowing diners to dip the noodles into the sauce before eating. Tsuyu can also be used as a dressing for salads or as a seasoning for various dishes. Its umami-rich flavor profile makes it a versatile addition to Japanese cuisine.
