Eel sauce, also known as unagi sauce or kabayaki sauce, is a thick, glossy, dark brown Japanese condiment. This umami-rich sauce boasts a complex flavor profile that is both sweet and savory, with a hint of saltiness and a slightly caramelized taste. Its viscous texture allows it to cling beautifully to grilled or broiled foods, adding a visually appealing sheen. Often used as a glaze or dipping sauce, eel sauce provides a delightful depth of flavor that enhances a variety of dishes. Its deep flavor comes from a base of soy sauce, mirin, sake, and sugar, which are reduced to create its signature rich flavor.

Eel sauce, especially if homemade or opened, should be stored in the refrigerator to prevent spoilage and maintain its quality. Ensure the bottle or container is tightly sealed. Refrigerated eel sauce typically lasts for several weeks to months. Check for any changes in smell, color, or consistency before using; discard if any abnormalities are detected. Unopened, commercially prepared eel sauce can usually be stored at room temperature according to the date on the label, but refrigeration after opening is crucial.
