Nikiri soy sauce is a seasoning made by heating soy sauce, mirin, and sake to evaporate the alcohol content, creating a mellow flavor. Applying it to sushi or sashimi toppings enhances the natural taste of the ingredients.
When I actually made and used nikiri soy sauce, the flavor was completely different from using regular soy sauce straight. Especially when you start with a high-quality soy sauce as the base, the depth of flavor after making nikiri soy sauce changes significantly.
Not only the ratio of ingredients but also the choice of which soy sauce to use initially is a crucial factor that determines the taste. Comparing the intensity and sweetness to suit your preferred sushi toppings makes the difference easier to notice.
