This is a basic sauce (tare) can be used all summer for grilling chicken. Yakitori is usually chicken on skewers: yaki
=grilling and tori
This basic sauce can be used for more than yakitori. Use portions of the sauce to grill: chicken, pork, fish, or just about anything you can cook over charcoal, food you cook on skewers, or not!
Add some orange juice, honey, fruit preserves, spices, and voila: teriyaki sauce.
