Eel sauce, also known as unagi sauce, is a sweet and savory condiment often used in Japanese cuisine. It is perfect for drizzling over grilled eel, sushi, or even as a dipping sauce. This simple recipe allows you to create a delicious homemade version with just a few ingredients.
One of the key ingredients in this recipe is mirin, a sweet Japanese rice wine. It may not be commonly found in every pantry, but it is essential for achieving the authentic flavor of eel sauce. Look for it in the Asian section of your supermarket or at a specialty Asian grocery store.

Ingredients For Eel Sauce Recipe
Soy sauce: A salty and savory liquid made from fermented soybeans, essential for the base flavor of the sauce.
Mirin: A sweet Japanese rice wine that adds a unique sweetness and depth to the sauce.
Sugar: Granulated sugar is used to balance the saltiness of the soy sauce and enhance the sweetness of the mirin.
Technique Tip for This Recipe
When making eel sauce, it's crucial to monitor the heat closely. Bringing the mixture to a boil over medium heat ensures that the sugar dissolves properly and integrates with the soy sauce and mirin. Once it reaches a boil, reducing it to a simmer allows the sauce to thicken without burning. Stir occasionally to prevent sticking and achieve a smooth, glossy consistency.

How to Store or Freeze This Sauce
Allow the eel sauce to cool completely before storing. This prevents condensation from forming inside the container, which can dilute the sauce and affect its flavor.
Transfer the cooled sauce into an airtight container. Glass jars or plastic containers with tight-fitting lids work best to maintain the sauce's freshness.
Label the container with the date of preparation. This helps you keep track of how long the sauce has been stored.
Store the container in the refrigerator. The eel sauce can last up to two weeks when properly refrigerated.
For longer storage, consider freezing the sauce. Pour the sauce into a freezer-safe container or ice cube trays for easy portioning.
If using ice cube trays, once the sauce is frozen, transfer the cubes to a resealable plastic bag or another airtight container. This saves space and makes it easy to thaw only what you need.
When ready to use, thaw the sauce in the refrigerator overnight or use the defrost setting on your microwave. Avoid thawing at room temperature to prevent bacterial growth.
Give the thawed eel sauce a good stir before using, as some ingredients may separate during freezing and thawing.
If you notice any changes in color, texture, or smell, discard the sauce. Freshness is key to maintaining the best flavor in your eel sauce.
How to Reheat Leftovers
Stovetop Method: Pour the leftover eel sauce into a small saucepan. Heat over low to medium heat, stirring occasionally. This method ensures even heating and helps maintain the sauce's consistency. Be careful not to overheat, as it can thicken too much or burn.
Microwave Method: Transfer the eel sauce to a microwave-safe bowl. Cover with a microwave-safe lid or plastic wrap, leaving a small vent. Heat on medium power in 15-second intervals, stirring in between, until the sauce reaches the desired temperature. This method is quick but requires attention to avoid overheating.
Double Boiler Method: Place the eel sauce in a heatproof bowl. Set the bowl over a pot of simmering water, ensuring the bottom of the bowl does not touch the water. Stir occasionally until the sauce is warmed through. This gentle heating method helps preserve the sauce's texture and flavor.
Oven Method: Preheat your oven to 250°F (120°C). Pour the eel sauce into an oven-safe dish and cover with aluminum foil. Heat for about 10-15 minutes, stirring halfway through. This method is useful if you're reheating a larger quantity of sauce.
Immersion Circulator Method: If you have a sous-vide setup, place the eel sauce in a vacuum-sealed bag or a zip-lock bag with the air removed. Submerge in a water bath set to 140°F (60°C) for about 20 minutes. This method ensures precise temperature control and even heating.
Best Tools for Making This Sauce
Saucepan: A medium-sized saucepan is essential for combining and heating the ingredients evenly.
Measuring cups: Use measuring cups to ensure you have the correct proportions of soy sauce, mirin, and sugar.
Wooden spoon: A wooden spoon is ideal for stirring the mixture as it heats, helping to dissolve the sugar and blend the ingredients.
Stovetop: The stovetop provides the heat source needed to bring the mixture to a boil and then reduce it to a simmer.
Timer: A timer will help you keep track of the 10 minutes needed for the sauce to thicken.
Heat-resistant container: After cooking, transfer the sauce to a heat-resistant container to cool before using.
How to Save Time on Making This Sauce
Measure ingredients ahead: Pre-measure the soy sauce, mirin, and sugar to streamline the cooking process.
Use a non-stick pan: A non-stick pan ensures the sauce doesn't stick and makes cleanup faster.
Simmer with a lid: Cover the pan to speed up the thickening process and prevent splatters.
Cool quickly: Pour the eel sauce into a shallow dish to cool it faster.
Batch cooking: Make a larger batch and store extra sauce in the fridge for future use.
