Kotteri Mirin is similar to traditional mirin, a sweet rice wine for cooking. Kotteri Mirin adds authentic Japanese flavor, mild sweetness and glaze to a variety of grilled, broiled, baked and sauteed foods. It gives teriyaki and sukiyaki the full-flavored sweetness for which theyre known. And because the sugar in Kotteri Mirin is already dissolved, it blends more easily with other ingredients. Restaurant quality product.
