Yamasa brewed soy sauce is a type of soy sauce that is specifically designed to be paired with raw fish, such as and sushi. It is made from a blend of soybeans, wheat, salt, and koji (a type of mold used in fermentation), and is aged for several months to develop its unique flavor and aroma. soy sauce is typically darker and less salty than regular soy sauce, and has a subtle umami flavor that enhances the natural taste of the fish. It is a delicate and versatile condiment that can be used as a dipping sauce for and sushi, as well as a seasoning for seafood dishes and salads. soy sauce is widely available in Japanese grocery stores and can also be purchased online. It is an essential ingredient for anyone who loves and sushi and wants to enjoy it in its purest form.
