Question: does eel sauce have eel in it?
Answer: Eel sauce is very simple, and does not contain any weird ingredient, such as eel. It consists of just soy sauce and sugar, and something to thicken it. In Japan, it might be denpun (starch). It is only called eel sauce, because it is used to put on fresh water eel (unagi) and salt water eel (anago).
