Eel Sauce (Unagi no Tare)

Eel sauce, or Unagi no Tare, is a thick, syrupy Japanese condiment known for its perfect balance of sweet and savory notes. Traditionally used for grilled eel, modern versions are versatile and can be made at home with common pantry staples, offering a deep umami flavor that complements a wide range of dishes beyond seafood.

  • Total Time: 25 minutes
  • Yield: About 3/4 cup (180ml) 1x

Ingredients

Scale
  • 1/2 cup soy sauce
  • 1/2 cup mirin
  • 1/4 cup sake (or dry white wine/water)
  • 1/4 cup granulated sugar

Instructions

  1. Step 1: Combine Ingredients – In a small saucepan, combine soy sauce, mirin, sake (or water), and granulated sugar.
  2. Step 2: Dissolve Sugar – Heat the mixture over medium-low heat, stirring constantly until the sugar has completely dissolved.
  3. Step 3: Simmer and Reduce – Bring the mixture to a gentle simmer. Do not boil vigorously. Continue to simmer for 15-20 minutes, or until the sauce has thickened to a syrupy consistency and reduced by about half. It should coat the back of a spoon.
  4. Step 4: Cool and Store – Remove the saucepan from the heat and allow the eel sauce to cool completely at room temperature. The sauce will thicken further as it cools. Transfer to an airtight container and store in the refrigerator for up to 2-3 weeks.

Notes

Despite the name, this versatile sauce does not contain eel in its modern form. It pairs beautifully with sushi, grilled meats, vegetables, and rice bowls. Its dark, almost black color comes from the caramelization of sugars during the cooking process.
