White miso soybean paste, light brown sugar, and two japanese rice wines are known as sake and mirin are blended together to make a flavorful miso marinade for broiled or baked fish or poultry. Miso, or fermented soybean paste, is a japanese condiment that comes in many varieties depending on the region they are from. They can be dark or light and taste sweet or salty. The most common kinds of miso are shiro (white) miso and aka (red) miso. Miso is not meant to be eaten out of a container as you might do with dip. The most common uses are for miso soup, sauces, marinades like this one, tofu and vegetable dishes. Sake is a japanese wine made from fermented rice. While sake can be quite potent, mirin is a low-alcohol sweet rice wine that some say helps mask the smell of fish and seafood.
