In this step, start by mixing soy sauce, barbeque sauce, brown sugar, rice vinegar, honey, black pepper, and sesame seed oil. Make sure that the mixture is ready to be added to a saucepan after the garlic and ginger are ready. Many people prefer using barbecue sauce on stir fry sauce recipes whenever they have it. However, you can also opt to use hoisin sauce as a substitute for a barbeque recipe.
