This sauce is made by blending Yamasa brand soy sauce with carefully selected spices and molasses in a meticulous ratio, providing chicken with a pleasant, sharp sweetness and umami flavor. It can also be used as a finishing sauce for fish and grilled vegetables. This beautiful, glossy yakitori sauce adds rich flavors from sugar, mirin, and chicken extract. Just before grilling, coat your barbecue ingredients with the thick, glossy sauce and grill again for a final, smoky finish.
