How To Make Eel Sauce – Fast and Easy Recipe

How To Make Eel Sauce: A couple of weeks ago, my boyfriend and I went out for sushi when we stumbled upon a truly delicious appetizer plate, which was a combination of crunchy rice and raw fish with an eel sauce drizzle.

He asked me what eel sauce was as he (literally) licked the plate clean of the dark brown syrup. I answered: It is similar to duck sauce in that it is named after a dish, but is not made of eel at all.

It was honestly the first time I was unfamiliar with what it was actually made of… or if I could replicate it at home.

Upon starting a search for eel sauce online, I discovered there isn’t much information available. There isn’t even a Wikipedia entry. Even searching indexes of Japanese cookbooks didn’t provide me with much information.

Since eel sauce is named for its use, I went looking for recipes of Japanese barbecue eel with a honey-like dark brown sauce. Thus, I found the eel sauce I was looking for, though not as I had anticipated.

When I realized that eel sauce is named for its purpose, I began searching for Japanese barbecue eel recipes… but discovered most ended with a dark brown sauce in the honey-like family. I had found exactly what I wanted, even if it wasn’t called that.

If you don’t have an option nearby, order it from Amazon.

Ingredients for Eel Sauce

I’m using 100ml of mirin, which is about 6 1/2 teaspoons, to add sweet and acidic notes and create a sticky texture.


I use 3 1/2 tablespoons to give the sauce a sweet taste and give it a sticky texture. You can always add more to the taste if you want it to be sweeter. I recommend adding 1 more teaspoon at a time after tasting.

Soy Sauce:

What better way to add umami to this sauce than with soy sauce. I’m using 100 ml, which will equal about 6 1/2 tablespoons.


Incorporate 2 1/2 tablespoons of cooking sake or your favorite sake to give the sauce a touch of fruitiness and bitterness.
