- 1/2 cup soy sauce
- 1/2 cup mirin (sweet rice wine)
- *(soy sauce : mirin = 1:1)
- 2 Tbsp sugar
Combine all ingredients in a saucepan. Stir the mixture well. Put it on medium heat and bring to a boil. Turn down the heat to low and simmer for a couple minutes. Stop the heat and cool the mixture. Store the sauce in a clean bottle in the refrigerator.*If you don’t have mirin, you can substitute sake and sugar for mirin. The ratio of sake to sugar is 3 to 1. Adjust the amount of sugar, depending on your preference.
