White Sumiso Sauce is a traditional sauce made from young, pale white miso or medium-aged light brown miso, sugar, and vinegar. It has a thick texture and a pleasant soybean flavor with delicious, sweet, sour, and salty characteristics... I use [this sauce] in traditional and modern Japanese preparations and also employ it as a new flavoring element in many popular American recipes, such as salad dressings, marinades, and rubs.
Freezing will not change the texture of the sauce, and prepared sauce can be stored in the freezer for up to three months. When needed, take it out of the freezer, quickly scoop and transfer the necessary portion to a small bowl, and return the container to the freezer to preserve the quality.
