How to Make It
In a saucepan set over medium heat, combine the soy sauce, mirin, ½ cup water, sake, and bonito flakes. Bring to a full rolling boil; then remove the pan from the heat and let cool. Strain the cooled sauce, discarding the solids. The sauce will keep in an airtight container in the fridge forever.
