Upgrade this simple, classic sauce by adding toasted sesame seeds, chopped scallions, sambal oelek, and/or freshly grated ginger.
Combine soy sauce, sake, mirin, and honey in a small saucepan. Bring to a boil, stirring until honey dissolves. Whisk 1 tablespoon cornstarch into 1/2 cup water; whisk into saucepan. Boil until sauce thickens and reaches desired consistency, about 8 minutes.
