Flavour for your soups, noodles and stews. Add rich umami flavour to your cooking with yamashin\'s top quality white soy sauce-based soup stock. Made by combining white soy sauce with umami-rich ingredients like bonito and mackerel fish flakes, dried sardines, and kombu kelp seaweed extract, this dashi tsuyu soup base will give your dishes all of the quintessential Japanese flavour they will need. As this tsuyu is made with white soy sauce, it is also paler in colour to most tsuyu and therefore more suitable for kaiseki ryori and other appearance-based cuisine.
