Ingredients
- 1/2 cup soy sauce
- 1/2 cup mirin
- 1/4 cup granulated sugar
Steps
- Bring soy sauce, mirin, and sugar to a simmer in a small saucepan over medium-low heat. Cook, stirring occasionally to dissolve sugar, until sauce coats the back of a spoon and is reduced to about 3/4 cup, 6 to 8 minutes. Remove from heat. Let cool to room temperature, about 15 minutes.
