What Is Eel Sauce
Eel sauce is Unagi no Tare (うなぎのたれ) in Japanese, and it is a thick and sweetened soy sauce. Traditionally, it is used on grilled eel or dishes that feature grilled eel, such as unagi don or unagi sushi and doesn’t contain eel. Although many commercial sauce brands are available, the best eel sauce is the homemade version.
What Does It Taste
It tastes savory-sweet from the sake, soy sauce, mirin, and sugar.
How to Make Eel Sauce
Making this sauce at home is as simple as one can imagine. You only need four ingredients – sake, mirin, sugar, and soy sauce, to create a rich, umami-packed sauce. Combine the mixture in a small pot and let it simmer until the sauce caramelizes and thickens to your desired richness.
The great thing about making the sauce instead of buying the bottled variety is you can decide on the balance of sweet and salty. Plus, there are no additives or preservatives.
Make Gluten-free Eel Sauce
Yes! Use Gluten-Free Soy Sauce to make the gluten-free version of the sauce!
How To Use
Aside from regular unagi dishes, unagi sauce is finger-licking delicious on BBQ. Think grilled meat, fish, tofu, mushrooms, and onigiri. All you need is a light brush or a drizzle of this sweet-savory sauce to heighten the flavor. In addition, you can use it as a marinade for meats or as a dressing for noodles.

Where To Buy
You can purchase the bottled variety in the condiment section of Japanese grocery stores and well-stocked Asian supermarkets. If that’s not an option, find it on Amazon.
