teriyaki sauce
What is teriyaki sauce exactly?
Well, it is a basic sauced used in Asian cooking. Traditionally teriyaki sauce is made with soy sauce, sake or mirin, ginger and sugar. It can be used as a marinade or to make a stir fry. The word comes from two Japanese words: teri meaning glazed, and yaki meaning grilled or broiled.
You can change the consistency by cooking it longer, in which case it will turn into a thick sauce.
You can certainly make your own by using the ingredients mentioned above. I have not experimented yet, but will do so in the next few months.
