Sweet & Savory Eel Sauce Recipe
Ingredients
- 1/2 cup soy sauce
- 1/2 cup mirin (or ½ cup water + 1 tsp sugar as a substitute)
- 1/4 cup sugar
- 2 tbsp sake (optional, adds depth)
- 1 tbsp cornstarch (optional, for thickening)
- 1 tbsp water (for cornstarch slurry if using)
Instructions
- Combine ingredients: In a small saucepan, mix soy sauce, mirin, sugar, and sake (if using). Stir until sugar dissolves.
- Simmer: Place over medium heat and bring to a low simmer. Stir occasionally to prevent burning.
- Thicken (optional): If you want a thicker sauce, mix cornstarch with 1 teaspoon water to make a slurry. Slowly whisk into the simmering sauce and cook 1–2 minutes until thickened.
- Taste & adjust: Check sweetness and saltiness. Add a little extra sugar or mirin if needed.
- Cool & store: Remove from heat, let it cool slightly, and use immediately or store in an airtight jar in the fridge for up to 2 weeks.

Step-by-Step Instructions

- Mix base ingredients: In a small saucepan, combine soy sauce, mirin, sugar, and sake (if using). Stir until sugar dissolves.
- Heat gently: Place over medium heat and bring to a low simmer. Stir occasionally to prevent burning.
- Optional thickening: If you like a thicker sauce, mix cornstarch with 1 teaspoon water, then slowly whisk into the simmering sauce. Cook for 1–2 minutes until it thickens.
- Taste & tweak: Adjust sweetness or saltiness to your liking. Want sweeter? Add a pinch more sugar. Too salty? Splash in more mirin or a tiny bit of water.
- Cool & store: Remove from heat and let cool slightly. Use immediately or store in a jar in the fridge for up to 2 weeks.
Common Mistakes to Avoid
- Burning the sugar: Keep heat moderate; burnt sugar = bitter sauce.
- Skipping cornstarch (if thick sauce wanted): Sauce will be thin, which is fine, but may not cling to sushi rolls.
- Not tasting: Saltiness varies by soy sauce brand. Taste as you go!
- Adding cornstarch too early: It clumps if added before the sauce is hot enough.
Alternatives & Substitutions
- Mirin substitute: Mix 1 tsp sugar + ½ cup water or use rice vinegar lightly.
- Sake substitute: Skip it or add a splash of apple juice for sweetness.
- Soy sauce swap: Low-sodium soy sauce works if you want a milder taste.
- Thickening: Honey or maple syrup can add sweetness and viscosity instead of cornstarch.
