1/3 cup soy sauce
1/3 cup rice wine or sake
4-1/2 tablespoons sugar
1-1/2 tablespoons minced frish ginger
1/2 teaspoon crushed dried red chilies (optional)
1-1/2 tablespoons cornstarch
1/3 cup water
Mix ingredients in a medium size saucepan, and heat until thickened, stirring constantly over medium heat with a wooden spoon to prevent lumps. Let cool.
I have used for marinade but this would also be a great dipping sauce.
