Classic Japanese Unagi Sauce is a glossy, lusciously thick and flavourful multi-purpose condiment made of just soy sauce, mirin, and sugar. These three simple ingredients are simmered together until shiny and sticky.
Whether drizzling over sushi, poke bowls, rice,or brushing on fish or chicken before, during, and after cooking, you’ll find yourself reaching for Eel Sauce all the time.

Ingredients
  

  • ½ cup soy sauce
  • ½ cup mirin
  • ½ cup granulated sugar

Optional:

  • Up to 2 teaspoons cornstarch for an extra thick sauce See Notes

Instructions
 

  • In a small saucepan over medium heat, whisk together the soy sauce, mirin, and sugar until the sugar is dissolved. Bring to a gentle boil.
  • Keep at a gentle boil until the sauce is reduced by about ⅓ of its original volume. You can test the doneness by dipping a spoon into the sauce and gently drawing your finger through it. If it stays clean where you pulled your finger through, the sauce is ready.
  • Remember that the sauce will thicken as it cools. This should have about the consistency of honey at room temperature.
  • Pour the sauce into a clean canning jar or other heat proof container and lid loosely. Allow it to cool to room temperature before fixing the lid on tightly and storing in the refrigerator for up to 2 weeks.

Notes

Unagi sauce is naturally about the consistency of honey at room temperature. If you’d prefer a much thicker eel sauce, you can up to 2 teaspoons of cornstarch with 2 tablespoons of water until it is dissolved. Pour into the hot eel sauce, whisking constantly, until the mixture returns to a boil. Boil gently, stirring constantly, for 2 minutes.
Pour into a jar and store as instructed above.
