Tsuyu no moto is a triple concentrated soup base by fortifying soy sauce with tremendous amounts of bonito flakes, sake, mirin, and kombu. Tsuyu is an essential condiment commonly used in soba and udon noodle dishes as the foundation of the dipping sauce. Tsuyu is also excellent as a building block for dressings, soups, and other sauces.
Uses: Dilute or use tsuyu as desired for tempura, gyudon, soba, udon, and simmered dishes. A simple ratio of 1:2 base to water is enough for most dips.
