- 1/4 cup mirin
- 1/4 cup sake
- 1/4 cup sugar
- 1 tablespoon cornstarch
- 2 tablespoons water
Ingredient Notes and Substitutions
- Soy Sauce: Provides saltiness and umami. Use tamari for gluten-free.
- Mirin: Adds sweetness and depth. Honey can be a substitute.
- Sake: Contributes to the sauce’s complexity. Use white wine or rice vinegar if unavailable.
- Sugar: Balances the flavors. Brown sugar can add a deeper flavor.
- Cornstarch: Thickens the sauce. Flour can be an alternative thickening agent.
How to Make Unagi Sauce
Step 1: Combine Ingredients
In a small saucepan, combine soy sauce, mirin, sake, and sugar. This creates the base of the sauce.
Step 2: Heat the Mixture
Place the saucepan over medium heat. Gently heat the mixture until the sugar dissolves, stirring occasionally.
Step 3: Prepare Cornstarch Slurry
In a small bowl, mix cornstarch with water until smooth. This will help thicken the sauce later.
Step 4: Add Slurry to Sauce
Once the sugar has dissolved, add the cornstarch slurry to the saucepan. This step is crucial for achieving that perfect glaze.
Step 5: Simmer the Sauce
Allow the sauce to simmer on low heat for about 5-10 minutes. This helps thicken the sauce and deepen the flavors.
Step 6: Stir Constantly
Stir the sauce constantly to prevent it from burning. It should become glossy and slightly thickened.
Step 7: Remove from Heat
Once the sauce reaches your desired thickness, remove it from the heat. Let it cool for a few minutes.
Step 8: Store the Sauce
Transfer the sauce to a storage container. Store it in the refrigerator for up to two weeks.
Pro Tip: For an extra depth of flavor, try adding a few drops of sesame oil just before serving.
Tips for the Best Unagi Sauce
- Use high-quality soy sauce for better taste.
- Keep an eye on the heat to avoid burning the sugar.
- Allow the sauce to cool before storing for optimal flavor.
- Double the recipe for batch cooking and long-term use.
- Try adding chopped green onions for a fresh kick.
Common Mistakes to Avoid
- Not stirring enough can lead to burning. Keep your whisk moving.
- Using low-quality soy sauce can ruin the flavor. Invest in a good one.
- Thickening too much will make the sauce unappetizing. Aim for a syrupy consistency.
- Skipping the cooling step can affect storage. Let it rest before sealing.
